Opinion for the court filed by Circuit Judge KAREN LeCRAFT HENDERSON.
Dissenting opinion filed by Circuit Judge SENTELLE.
KAREN LeCRAFT HENDERSON, Circuit Judge:
John D. Barnes (Barnes) appeals his conviction under 18 U.S.C. § 922(g)(9), which makes it unlawful for a person convicted of a “misdemeanor crime of domestic violence” to possess firearms or ammunition. Barnes challenges whether his 1998 assault conviction under D.C.Code § 22-504(a) constitutes a “misdemeanor crime of domestic violence” as defined in 18 U.S.C. § 921(a)(33)(A) because section 22-504(a) does not include as an express element of the offense any relationship between the offender and the victim. Our sister circuits that have addressed this question have rejected Barnes’s reading of section 921(a)(33)(A). It is an issue of first impression for us. Barnes also raises several constitutional challenges to his firearms conviction. While section 921(a)(33)(A) is not a paradigm of precise draftsmanship, we nonetheless join the other circuits in concluding that section 921(a)(33)(A) does not require the predi[1357]*1357cate “misdemeanor crime of domestic violence” to contain as an express element a relationship between the offender and his victim.
I.
On August 5, 1997 Barnes was charged in D.C. Superior Court with assault under D.C.Code § 22-504(a).1 The charging information alleged that on or about July 21, 1997 Barnes unlawfully assaulted Keisha Ellis, who, Barnes ultimately acknowledged, is his son’s mother. See Charging Information in No. M-11747-97; January 14, 1998 Transcript in No. M-11747-97 at 16. After pleading guilty to the charge, Barnes was sentenced to a prison term of 180 days, execution of which was suspended on the condition of a one-year period of probation. The judgment and commitment/probation order required Barnes to observe standard conditions of probation and, in particular, to enroll in and complete the local court’s domestic violence intervention program. See May 5, 1998 Judgment and Commitment Order at 1.
On August 17, 2000 an officer of the Metropolitan Police Department observed a vehicle being driven by Barnes. A paper trash bag obscured the right rear vent window. See 8/22/00 Tr. at 6. Believing that the car was stolen, the officer made a traffic stop and ran a search on Barnes’s driver’s license. The search revealed that he did not have a valid license. Upon placing Barnes under arrest for driving without a permit, the police officer conducted a search and discovered that Barnes had two .45 caliber bullets in his left pocket. See 8/22/00 Tr. 6-7. Another officer, who arrived at the scene before Barnes’s arrest, searched the car and found a loaded and operable Sig Sauer .45 caliber pistol underneath the driver’s seat. After a records check revealed that Barnes had been convicted of assault under D.C.Code § 22-504(a), see D.C. Superior Court Case No. M-11747-97, Barnes was charged with the unlawful and knowing receipt and possession of a firearm and ammunition in violation of 18 U.S.C. § 922(g)(9). See Information in Cr. No. 00-295. On October 6, 2001 pursuant to a plea agreement, Barnes entered a conditional guilty plea to the one-count criminal information'. In accordance with Fed. R.Crim.P. 11(a)(2), his plea agreement explicitly reserved his right to challenge whether his May 5, 1998 assault conviction constituted a “misdemeanor crime of domestic violence” as defined in 18 U.S.C. § 921(a)(33)(A). Plea Agreement in United States v. Barnes, Cr. No. 00-0295 at 2.
On February 1, 2001 Barnes filed a brief in district court, raising the statutory claim explicitly reserved in his plea agreement, see February 1, 2001 Defendant’s Memorandum of Law (App. 20-58), along with an unopposed motion to supplement that claim with several constitutional arguments. See February 1, 2001 Defendant’s Unopposed Motion to Supplement (App. 16-19). Barnes maintained that his assault conviction under D.C.Code § 22-504(a), which “does not include the relational element set forth in 18 U.S.C. § 921(a)(33)(A),” does not qualify as a “misdemeanor crime of domestic violence” under section 922(g)(9). February 1, 2001 Defendant’s Memorandum of Law at 3-6 (App. 22-25). He also claimed that his conviction violated “principles of equal protection contained in the Due Process [1358]*1358Clause of the Fifth Amendment” and that section 922(g)(9), read in conjunction with 18 U.S.C. § 921(a)(33)(A), was “unconstitutionally vague.” Id. at 6-7. The government opposed Barnes’s claims. See February 27, 2001 Government Memorandum of Law (App. 59-66).
On March 19, 2001 the district court held that Barnes’s “conviction in the Superior Court of the District of Columbia in Criminal Case No. M-11747-97 for simple assault under D.C.Code § 22-504 constitutes a ‘misdemeanor crime of domestic violence’ within the meaning of 18 U.S.C. § 921(a)(33)(A) and can thus serve as a predicate for conviction under 18 U.S.C. § 922(g)(9).” March 19, 2001 Order at 1 (App. 76). Regarding the statutory question, the district court adopted the reasoning of the First and Eighth Circuits, stating that “[h]ad Congress intended to require the prosecution to prove as elements of the offense both the use of force and the relationship of the defendant to the victim, it surely could have done so by using the plural, ‘elements,’ rather than the singular, ‘element,’ when writing § 921(a)(33)’s definition of a misdemeanor crime of domestic violence.” See March 19, 2001 Memorandum Opinion at 4 (citing United States v. Meade, 175 F.3d 215, 218-20 (1st Cir.1999), and United States v. Smith, 171 F.3d 617, 619-20 (8th Cir.1999)). The district court also rejected Barnes’s constitutional challenges. See March 19, 2001 Memorandum Opinion at 7-11. On April 17, 2001 the district court sentenced Barnes to a term of imprisonment of twelve months and one day, followed by two years’ supervised release as well as a special assessment of $100. 4/17/01 Tr. 7. Barnes filed a timely notice of appeal and the district court stayed execution of the sentence pending appeal.
II.
Because the district court’s ruling involved solely questions of law, our review is de novo. See Butler v. West, 164 F.3d 634, 639 (D.C.Cir.1999) (citations omitted); United States v. Popa, 187 F.3d 672, 674 (D.C.Cir.1999) (citations omitted) (first amendment challenge subject to de novo review).
A Elements of “Misdemeanor Crime of Domestic Violence”
In 1996, the Congress amended the Gun Control Act of 1968,' 18 U.S.C. § 922 (1994), by providing that:
It shall be unlawful for any person ... who has been convicted in any court of a misdemeanor crime of domestic violence, ... to ship or transport in interstate or foreign commerce, or possess in or affecting commerce, any firearm or ammunition; or to receive any firearm or ammunition which has been shipped or transported in interstate commerce.
18 U.S.C. § 922(g)(9). Section 921 of Title 18, entitled “Definitions,” provides in pertinent part:
the term “misdemeanor crime of domestic violence” means- an offense that—
(i) is a misdemeanor under Federal or State law; and
(ii) has, as an element, the use or attempted use of physical force, or the threatened use of a deadly weapon, committed by a current or former spouse, parent, or guardian of the victim, by a person with whom the victim shares a child in common, by a person who is cohabitating with or has cohabitated with the victim as a spouse, parent, or guardian, or by a person similarly situated to a spouse, parent, or guardian of the victim
[1359]*135918 U.S.C. § 921(a)(33)(A).2
Barnes asserts that the definition of “misdemeanor crime of domestic violence” set forth in section 921(a)(33)(A) requires the predicate offense to “contain, ‘as an element,’ not only the ‘use or attempted use of physical force ... ’ but also that the use of force be ‘committed by’ a person who maintained a domestic relationship with the victim, as specifically defined in the statute.” See Barnes’s Br. at 7-8. The government responds that “the text and legislative purpose” demonstrate that section 921(a)(33)(A) “does not require that the necessary domestic relationship be established as an element of the predicate offense.” Gov’t Br. at 12-13.
In construing a statute, we look first for the plain meaning of the text. If the language of the statute has a “plain and unambiguous meaning,” our inquiry ends so long as the resulting “statutory scheme is coherent and consistent.” See United States v. Wilson, 290 F.3d 347, 352 (D.C.Cir.2002) (quoting Robinson v. Shell Oil Co., 519 U.S. 337, 340, 117 S.Ct. 843, 846, 136 L.Ed.2d 808 (1997) (internal quotations omitted)). Whether statutory language is plain depends on “the language itself, the specific context in which that language is used, and the broader context of the statute as a whole.” Id. (quoting Robinson, 519 U.S. at 341, 117 S.Ct. at 843).
Both sides agree that D.C.Code § 22-504(a) constitutes a “misdemeanor under ... State Law” within the meaning of section 921(a)(33)(A)(i). Barnes and the government also agree that section 921 (a)(33)(A)(ii) requires that a “misdemeanor crime of domestic violence” contain “as an element” “the use or attempted use of physical force, or the threatened use of a deadly weapon.” 18 U.S.C. § 921 (a)(33)(A)(ii). Moreover, there is no dispute that section 22-504(a) of the D.C.Code, contains a similar element.3 It also appears undisputed that Barnes and the victim of his assault, Keisha Ellis, had a son together at the time of the assault and thus share one of the domestic relationships included in section 921 (a)(33)(A)(ii) (“committed ... by a person with whom the victim shares a child in common”). See February i, 2001 Defendant’s Memorandum of Law at 2 (“Mr. Barnes shares a child in common with the complaintant [sic] in M-11747-97”) (App. 21); February 1, 2001 Defendant’s Memorandum of Law Exh. 3 at 16 (App. 45) and 22 (App. 51). Barnes contends, however, that the applicable relationship is an express element of the predicate offense be-' cause the prohibited “use of force” must be “committed” by a person with that relationship. Having been convicted of assault under D.C.Code § 22-504(a), which does not require a relationship between offender and victim, Barnes argues that his subsequent possession of a firearm is not prohibited by section 922(g)(9) because he has not been convicted of a “misdemeanor crime of domestic violence.” While the domestic relationship requirement of section 921(a)(33)(A)(ii) must unquestionably be established in a section 922(g)(9) prose-[1360]*1360ration, the dispute here is whether the predicate offense must itself expressly include the requirement.
The premise of Barnes’s reading of section 921 (a)(33)(A)(ii) is that the “committed by” language modifies the “use of force” clause immediately preceding it and thus is included in the “element” that a “misdemeanor crime of domestic violence” must contain. Barnes refers to what is known as the “Rule of the Last Antecedent,” whereby “[ojrdinarily, qualifying phrases are to be applied to the words or phrase immediately preceding and are not to be construed as extending to others more remote.” United States v. Pritchett, 470 F.2d 455, 459 & n. 9 (D.C.Cir.1972). Accordingly, Barnes argues that the “committed by” phrase modifies the “use of force” element because the latter immediately precedes the former within subpart (ii). As was noted in Pritchett, however, “the Rule of Last Antecedent is not an inflexible rule, and is not applied where the context indicates otherwise.” Id. at 459. Here, context is everything. Bearing in mind that, “when construing a statute, we are obliged to give effect, if possible, to every word Congress used,” Murphy Exploration & Prod. Co. v. U.S. Dept. of Interior, 252 F.3d 473, 481 (D.C.Cir.2001) (quoting Reiter v. Sonotone Corp., 442 U.S. 330, 339, 99 S.Ct. 2326, 2331, 60 L.Ed.2d 931 (1979)); see also Alabama Power Co. v. EPA, 40 F.3d 450, 455 (D.C.Cir.1994) (“[sjtatutory text is to be interpreted to give consistent and harmonious effect to each of its provisions”), we must determine if “committed by” can, consistent with its meaning, modify “use of force.” The verb “commit” means “to do (something wrong or reprehensible), to perpetrate, be guilty of (a crime or offence, etc.).” Oxford English Dictionary 559 (2d ed.1989) (emphasis added). The use of force is not “committed,” “done” or “perpetrated.”4 An “offense” is “committed” or “perpetrated.” And here, the offense of a “misdemeanor crime of domestic violence” must be committed by a person in one of the specific relationships. Subpart (ii) of section 921(a)(33)(A) is not a complete sentence— subsection 921(a)(33)(A) is itself one sentence that begins with “[ejxcept as otherwise provided in subparagraph (C), the term ‘misdemeanor crime of domestic violence’ means an offense that — ” and continues through subparts (i) and (ii).5 In short, a “misdemeanor crime of domestic violence” means an offense that is a misdemeanor, has, as an element, the use of force and was committed by a person with the requisite relationship. An illustration using simpler language demonstrates the point. If the statute read
“larceny means an offense that has, as an element, monetary gain, committed by a person ...,”
it would be obvious that “committed” modifies “offense” and that monetary gain is the only “element.” Just as “monetary gain” is not “committed,” the “use of force” is not “committed.” The “offense” is “committed.”6
[1361]*1361Barnes argues that if the Congress had intended the predicate offense to include only the “use of force” as an express element, it would have inserted the words “and was” before “committed by” and placed the remainder of (ii) in a subpart numbered (iii). Barnes Br. at 11. Needless to say, if the Congress had more precisely articulated its intention, our task would have been easier. In interpreting a statute, however, we are to determine its true, natural meaning, where ascertainable, irrespective of cumbersome syntax. See United States v. Moore, 613 F.2d 1029, 1040 (D.C.Cir.1979) (“or” read as conjunctive because “strict grammatical construction will frustrate legislative intent” evinced by legislative history and statutory purpose); United States Nat’l Bank of Oregon v. Indep. Ins. Agents of America, Inc., 508 U.S. 439, 454-55, 113 S.Ct. 2173, 2182, 124 L.Ed.2d 402 (1993) (purported “plain-meaning” analysis based only on punctuation inadequate where “deployment of quotation marks” points in one direction and “all of the other evidence from the statute points the other way”); cf. United States v. Shreveport Grain & Elevator Co., 287 U.S. 77, 82-83, 53 S.Ct. 42, 44, 77 L.Ed. 175 (1932) (“To determine the intent of the law, the court, in construing a statute will disregard the punctuation, or will repunctuate, if that be necessary, in order to arrive at the natural meaning of the words employed.”). In a Ninth Circuit decision, Longview Fibre Co. v. Rasmussen, 980 F.2d 1307 (9th Cir.1992), the court analyzed the following language of the Clean Water Act: “in approving or promulgating any effluent limitation or other limitation under section 1311, 1312, 1316, or 1345 of this title.” Id. at 1310 (quoting 33 U.S.C. § 1369(b)(1)(E)). The critical question, the court declared, was “[d]oes the modifier reach back?” In other words, do the listed sections modify “other limitation” only or “any effluent limitation” as well? It first noted that “[g]rammatically, either interpretation could be correct, and the [first] interpretation would more likely be right. ‘Subordinate clauses should be placed near the words they modify.’ Margaret Shertzer, The Elements of Grammar 47 (1986). That is why we say, ‘As I was flying into Ketchikan, I saw a pod of whales,’ not T saw a pod of whales flying into Ketchi-kan.’ ” Id. at 1310-11. In concluding that the modifier does indeed reach back, the court stated:
Syntax cannot always control construction. The legislative process may have subordinated clear writing to some other goal. We must examine the meaning of the words to see whether one construction makes more sense than the other as a means of attributing a rational purpose to Congress. Read for rational purpose, the syntactically disfavored ’ Construction of section 1369(b)(1)(E) is sensible, the other as unlikely as the flying whales.
Id. at 1311. The fact that the Congress somewhat awkwardly included the “committed by” phrase in subpart (ii) (instead of adding a subpart (iii)) is not significant in view of the ^natural reading that would' result if “committed by” were construed to modify “use of force.”7
[1362]*1362The dissent questions the majority’s adoption of a construction of section 921(a)(33)(A)(ii) that was not advanced by the government, namely that “committed” modifies “offense.” See Dissent op. at 1370. But the meaning of the statute is “the issue ... properly before the court,” Kamen v. Kemper Fin. Servs., Inc., 500 U.S. 90, 99, 111 S.Ct. 1711, 1718, 114 L.Ed.2d 152 (1991),8 and thus “the court ..., retains the independent power to identify and apply the proper construction of governing law.” Id. (emphasis added). Alluding' briefly to the merits, the dissent rejects what it refers to as “the majority’s ipse dixit.” Dissent op. at 1370. “Ipse dixit” means a “bare assertion resting on the authority of an individual.” Black’s Law Dictionary 961 (4th ed.1968). The “individuals” on whose authority the majority rests for the meaning of “committed” are the Oxford English Dictionary and Merriam-Webster’s Third New International Dictionary. See supra at 1360. Our dissenting colleague declares that it “cannot be gainsaid that the language of this statute is ambiguous,” adding that the majority opinion is “rife with allusions to its ambiguity.” Dissent op. at 1369. The dissent has not read the majority opinion carefully. As the foregoing discussion manifests, we refer to imprecision (not “ambiguity”) only in connection with the syntax of the statute, not with the meaning of the language used.
That the district court as well as every other court that has considered the issue concluded, albeit on a different basis, that section 921(a)(33)(A)’s language plainly requires only one element, i.e., the use of force, further bolsters our interpretation. See March 19, 2001 Memorandum Opinion at 4; United States v. Chavez, 204 F.3d 1305, 1313-14 (11th Cir.2000) (concluding that conviction under 18 U.S.C. § 113(a)(4), general assault statute for U.S. territories, constitutes “misdemeanor crime of domestic violence”); United States v. Meade, 175 F.3d 215, 218-19 (1st Cir.1999) (defendant’s state misdemeanor conviction for assaulting his spouse, under Massachusetts’s general assault and battery statute, is “misdemeanor crime of domestic violence,” within 18 U.S.C. §§ 921(a)(33)(A), 922(g)(9)); United States v. Smith, 171 F.3d 617, 620 (8th Cir.1999) (conviction under Iowa misdemeanor simple assault statute' for defendant’s assault of mother of his child constitutes “misdemeanor crime of domestic violence”); United States v. Thomson, 134 F.Supp.2d 1227, 1230 (D.Utah 2001); United States v. Meade, 986 F.Supp. 66, 68 (D.Mass.1997); United States v. Smith, 964 F.Supp. 286, 291-92 (N.D.Iowa); see also United States v. Ball, 7 Fed.Appx. 210, 213, 2001 WL 324624 (4th Cir.2001), cert. denied, 122 S.Ct. 226 (2001) (unpublished per curiam order). These courts found the Congress’s use of the singular “element” rather than “elements” determinative. As the district court in Meade stated:
The crux of the matter is whether the phrase “as an element” modifies both requirements or just the use of force requirement. The inclusion of both the use of force and domestic relationship requirements in one sentence does not mandate that they be treated as one element. In drafting the statute Con[1363]*1363gress placed the singular word “element” immediately before the use of force requirement. In choosing the singular word “element,” Congress intended to modify only the language immediately following the phrase. If Congress had intended that both requirements be mandatory elements of the underlying state statute the word “element” would have been in the plural to encompass both requirements. Reading the phrase “has, as an element” in its ordinary plain meaning, it is clear the singular “element” modifies only the use of force requirement.
Meade, 986 F.Supp. at 68. Barnes counters that if, as he contends, the “committed by” language modifies the use of force clause, “Congress could have reasonably viewed the two factual requirements as a single element.” Barnes Br. at 12. Under this view, the use of the singular element is not determinative because a qualifying “misdemeanor crime of domestic violence” simply has one element with two subparts. To be sime, the Congress has used the singular “element” when referring to more than one factor in other provisions of Title 18. See, e.g., 18 U.S.C. § 16(a) (defining “crime of violence” as “an offense that has as an element the use, attempted use, or threatened use of physical force against the person or property of another”(emphasis added)). Nonetheless, while a “crime of violence” may have a necessarily two-pronged single “element,” namely (1) use of force (2) against another’s person or property, the singular “element” used in section 921(a)(33)(A)(ii) is followed by two independent, and unlinked, factors, the use of force and the perpetrator’s relationship to the victim.9 Our research has revealed that section 921(a)(33)(A) of Title 18 appears to be the only federal criminal statute in which the “has, as an element,” language is set off by commas. In addition, that the “committed by” language is itself separated from the “use of force” language by a comma (as well as by the clause “or the threatened use of a deadly weapon”) reinforces the separateness of the “use of force” element from the “committed by” language. In defining crimes that have more than one distinct element, the Congress generally uses the phrase “has as its elements” (emphasis added). See, e.g., 18 U.S.C. § 3559(2)(A) (“the term ‘assault with intent to commit rape’ means an offense that has as its elements engaging in physical contact with another person or using or brandishing a weapon against another person with intent to commit aggravated sexual abuse or sexual abuse”).10 [1364]*1364While we do not necessarily find the singular versus plural rationale determinative, it does support our interpretation of section 921 (a) (33) (A.) (ii) as requiring that a “misdemeanor crime of domestic violence” include only the use of force as an element.
We are also influenced by the fact that Barnes’s interpretation of section 921 (a)(33)(A)(ii) would create a “significant practical anomaly,” rendering the law a nullity in a majority of the states as well as at the Federal level. Meade, 175 F.3d at 220. A “statute should ordinarily be read to effectuate its purposes rather than frustrate them.” See, e.g., Motor Vehicle Mfrs. Ass’n of U.S., Inc. v. Ruckelshaus, 719 F.2d 1159, 1165 (D.C.Cir.1983) (citations omitted).11 Section 922(g)(9) of Title 18, known as the “Lautenberg Amendment,” 142 Cong. Rec. D927-02, *D928 (1996), was enacted in order to remedy the nationwide problem that those convicted of a felony involving domestic assault were prohibited from firearms possession while those convicted of a misdemeanor involving domestic assault were not. In explaining the law’s disparate treatment of a person convicted of a domestic assault misdemeanor, Senator Lautenberg stated:
Under current Federal law, it is illegal for persons convicted of felonies to possess firearms. Yet, many people who engage in serious spousal or child abuse ultimately are not charged with or convicted of felonies. At the end of the day, due to outdated laws or thinking, perhaps after a plea bargain, they are, at most, convicted of a misdemeanor.... Often acts of serious spouse abuse are not even considered felonies.... This amendment would close this dangerous loophole and keep guns away from violent individuals who threaten their own families[.]
142 Cong. Rec. S10377-01, *S10377-78 (1996). Fewer than half of the states currently have a “domestic assault” statute that expressly includes as elements both the use of force and a specific relationship between the offender and victim.12 Most states, and the District of Columbia, charge domestic violence offenders under general assault statutes. Under Barnes’s construction, the Congress remedied one disparity — between felony and misdemean- or domestic violence convictions — while at the same time creating a new disparity among (and sometimes, within) states. A person who abused his spouse in a state with a domestic assault statute would lose the right to possess a firearm while a person who engaged in the same conduct but was convicted of simple assault would not. Moreover, Barnes’s interpretation would make section 921(a)(33)(A)(i)’s reference to a misdemeanor under “Federal law” a nullity because there is no federal misdemeanor that includes both the use of [1365]*1365force and the domestic relationship as express elements. See, e.g., 18 U.S.C. § 113(a)(4) (misdemeanor simple assault within maritime or territorial jurisdiction of the United States).
The legislative history of the Lautenberg Amendment confirms what the natural meaning of the statutory language reveals, namely that the “has as an element” language refers solely to the use of force. We “do not resort to legislative history to cloud a statutory text that is clear,” which we believe section 921(a)(33)(A) to be. Were it unclear, we could look to legislative history to “shed new light on congressional intent.” U.S. Telecom Ass’n v. FBI, 276 F.3d 620, 625 (D.C.Cir.2002) (internal quotations omitted). In describing the legislation’s enforcement provisions, Senator Lautenberg foresaw the statutory construction question central to this case:
Mr. President, the final agreement does not merely make it against the law for someone convicted of a misdemeanor crime of domestic violence from possessing firearms. It also incorporates this new category of offenders into the Brady law, which provides for a waiting period for handgun purchases. Under the Brady law, local law enforcement authorities are required to make reasonable efforts to ensure that those who are seeking to purchase a handgun are not prohibited under Federal law from doing so. Mr. President, convictions for domestic violence-related crimes often are for crimes, such as assault, that are not explicitly identified as related to domestic violence. Therefore, it will not always be possible for law enforcement authorities to determine from the face of someone’s criminal record whether a particular misdemeanor conviction involves domestic violence, as defined in the new law.
142 Cong. Rec. S11872-01, *S11878 (1996) (emphasis added). See North Haven Bd. of Educ. v. Bell, 456 U.S. 512, 526-27, 102 S.Ct. 1912, 1920-21, 72 L.Ed.2d 299 (1982) (“remarks ... of the sponsor of the language ultimately enacted, are an authoritative guide to the statute’s construction”); see also Amalgamated Transit Union v. Skinner, 894 F.2d 1362, 1370 n. 6 (D.C.Cir.1990). His statements express the unmistakable intent that a “misdemeanor crime of domestic violence” need not expressly include a domestic relationship element.
The legislative history also reveals that the “has, as an element, the use or attempted use of physical force, or the threatened use of a deadly weapon” language was added to the statute shortly before the provision was enacted. Replacing the originally proposed language that defined the predicate offense as a “crime of violence,” Senator Lautenberg explained that the addition of the “as an element” language was not intended to apply to the domestic relationship language:
Under the final agreement, the ban applies to crimes that have, as an element, the use or attempted use of physical force, or the threatened use of a deadly weapon. This is an improvement over the earlier version, which did not explicitly include within the ban crimes involving an attempt to use force, or the threatened use of a weapon, if such an. attempt or threat did not also involve actual physical violence. In my view, anyone who attempts or threatens violence against a loved one has demonstrated that he or she poses an unacceptable risk, and should be prohibited from possessing firearms.
142 Cong. Rec. S11872-01.13 Based on our “natural meaning” reading of the text, we [1366]*1366reject Barnes’s interpretation of section 921(a)(33)(A)(ii) and conclude instead that his conviction under D.C.Code § 22-504(a) qualifies as a “misdemeanor crime of domestic violence” within the meaning of the Lautenberg Amendment.14

Barnes contends the district court’s interpretation of section 921 (a) (3 3) (A) (ii) renders it unconstitutionally vague because “there is no way for a person to know from its language whether the relational requirement is an element of the predicate crime.” Barnes Br. at 16. He further argues that the relationship requirement itself is infirm because “a defendant convicted of simple assault cannot be sure whether he or she might later be held to be a ‘guardian’ of the victim ... or ‘similarly situated’ to a spouse, parent, or guardian of the victim.” Id. at 17. A similar argument has been rejected by two circuit courts. See Meade, 175 F.3d at 222 (section 921 (a)(33)(A)(ii) contains no ambiguity as to either persons to whom prohibitions apply or proscribed conduct); Smith, 171 F.3d at 623 (rejecting vagueness challenge).
To decide a vagueness challenge, we must assess whether it “either forbids or requires the doing of an act in terms so vague that men of common intelligence must necessarily guess at its meaning and differ as to its application.” United States v. Lanier, 520 U.S. 259, 266, 117 S.Ct. 1219, 1225, 137 L.Ed.2d 432 (1997). We have noted before that “the Constitution does not require unattainable feats of statutory clarity.” Hutchins v. District of Columbia, 188 F.3d 531, 546 (D.C.Cir.1999) (quotations omitted). As the Eighth Circuit in Smith declared, “[w]e would be hard pressed to find an individual of common, or even not so common, intelligence who could not determine whether he was in one of the enumerated relationships when he committed a misdemeanor crime including an element of physical force.” 171 F.3d at 623. Barnes’s alternative interpretation of the statutory text does not by itself establish vagueness. “Since words, by their nature, are imprecise instruments, even laws that easily survive vagueness challenges may have gray areas at the margins.” United States v. Nason, 269 F.3d 10, 22 (1st Cir.2001) (“use of force” in § 921 (a) (33) (A) (ii) not unconstitutionally vague) (citing United States v. Wurzbach, 280 U.S. 396, 399, 50 S.Ct. 167, 169, 74 L.Ed. 508 (1930)). We conclude that section 921(a)(33)(A)(ii) is sufficiently clear to reject Barnes’s vagueness attack.
C. Due Process
Barnes further argues that section 922(g)(9) violates his due process right under the Fifth Amendment because it does not require the government to prove, as an element of the offense, that he knew his possession of a firearm was illegal. A long line of circuit courts has rejected this argument. See, e.g., United States v. Mitchell, 209 F.3d 319, 322 (4th Cir.) (citing Bryan v. United States, 524 U.S. 184, 192, 118 S.Ct. 1939, 1945, 141 [1367]*1367L.Ed.2d 197 (1998), cert. denied, 531 U.S. 849, 121 S.Ct. 123, 148 L.Ed.2d 78 (2000)). Moreover, Barnes did not adequately raise this argument below and, thus, we review it for plain error only.15
As we already noted, section 922(g)(9) requires the defendant to “knowingly” violate the statute. See supra at 1359 n. 2. The Supreme Court has made clear that “the knowledge requisite to knowing violation of a statute is factual knowledge as distinguished from knowledge of the law.” Bryan v. United States, 524 U.S. 184, 192, 118 S.Ct. 1939, 1945, 141 L.Ed.2d 197 (1998) (internal quotation marks omitted). The Bryan Court concluded that “unless the text of the statute dictates a different result, the term ‘knowingly’ merely requires proof of knowledge of the facts that constitute the offense.” Id. at 193, 118 S.Ct. at 1946. The rule in Bryan has been applied by other circuit courts without exception in interpreting section 924(a)(2), which requires that a section 922(g)(9) offense be “knowingly” committed. See, e.g., United States v. Bostic, 168 F.3d 718, 722-23 (4th Cir.1999), cert. denied, 527 U.S. 1029, 119 S.Ct. 2383, 144 L.Ed.2d 785 (1999); United States v. Beavers, 206 F.3d 706, 708-09 (6th Cir.2000); United States v. Meade, 175 F.3d 215, 226 n. 5 (1st Cir.1999). Barnes knowingly possessed the firearm and that is the only knowledge required to convict him. He argues, however, that section 922(g)(9) falls within the narrow exception carved out by the holding in Lambert v. State of California, 355 U.S. 225, 228-30, 78 S.Ct. 240, 242-43, 2 L.Ed.2d 228 (1957). See Barnes Br. at 19. LambeH involved a city ordinance that made it a crime for any felon to remain in Los Angeles for more than five days without registering with the police. Lambert, 355 U.S. at 226-27, 78 S.Ct. at 241-42. The.Supreme Court reversed the defendant’s conviction on due process grounds because the city failed to establish that the defendant had notice that her “wholly passive conduct” could constitute a crime. Id. at 228, 78 S.Ct. at 243. Barnes contends that section 922(g)(9) is a similar statute that subjects to criminal prosecution an individual engaged in otherwise innocent conduct — possession of a firearm. The salient fact in LambeH, however, was that the defendant had no reason to know, or even to attempt to discover, that she was required to register in order to continue living in Los Angeles. Other circuit courts that have addressed this argument have uniformly rejected it. The Sixth Circuit’s observation in United States v. Beavers is instructive:
We conclude that Beavers’s conviction on a domestic violence offense sufficiently placed him on notice that the government might regulate his ability to own or possess a firearm. As noted in [United States v.] Baker[, 197 F.3d 211 (6th Cir.1999)] and Meade, domestic abuse is a well-known problem, and it should not surprise anyone that the government has enacted legislation in an attempt to limit the means by which persons who have a history of domestic violence might cause harm in the future.
206 F.3d at 710. Having been convicted of a violent crime, Barnes had reason to know that the government could regulate his possession of firearms and thus he cannot avail himself of the limited LambeH exception.16

D. Equal Protection
Section 921(a)(33)(B)(ii) provides an exception to section 922(g)(9) “if the conviction has been expunged or set aside, or is an offense for which the person has been pardoned or has had civil rights restored (if the law of the applicable jurisdiction provides for the loss of civil rights under such an offense).” In the District of Columbia, as in most states, an individual convicted of a misdemeanor does not forfeit his civil rights. Barnes argues that he is thus in a worse position than a person convicted in a jurisdiction that authorizes the loss of civil rights but can also restore them. Claiming that there is no rational basis for this distinction, he asserts that his conviction violates equal protection. See Barnes Br. at 21 (citing Bolling v. Sharpe, 347 U.S. 497, 499, 74 S.Ct. 693, 694, 98 L.Ed. 884 (1954)). His claim is without merit.
Because domestic violence misdemeanants are not a suspect class for equal protection purposes and because no “fundamental right” is implicated, the classification will be upheld “if there is any reasonably conceivable state of facts that could provide a rational basis for the classification.” Fraternal Order of Police v. United States, 173 F.3d 898, 903 (D.C.Cir.) (quotations omitted), cert. denied, 528 U.S. 928, 120 S.Ct. 324, 145 L.Ed.2d 253 (1999). The Congress’s decision to incorporate state law governing forfeiture of civil rights was rational irrespective of differences among states regarding restoration. Furthermore, the Congress provided other methods such as expungement and pardon that Barnes might use to come within the exception of section 921(a)(33). See McGrath v. United States, 60 F.3d 1005, 1008 (2d Cir.1995), cert. denied, 516 U.S. 1121, 116 S.Ct. 929, 133 L.Ed.2d 857 (1996).
For the foregoing reasons, we affirm the district court’s holding that Barnes’s conviction of assault under D.C.Code § 22-504(a) constitutes a “misdemeanor crime of domestic violence” within the meaning of 18 U.S.C. § 921(a)(33)(A) and thus validly serves as a predicate offense for his conviction under 18 U.S.C. § 922(g)(9).
So ordered.
