(a) ATTHETRIAL. A juror may not testify as a witness before the
other jurors at the trial. If a juror is called to testify, the court
must give a party an opportunity to object outside the jury’s pres-
ence.
(b) DURING AN INQUIRY INTO THE VALIDITY OF A VERDICT OR IN-
DICTMENT.
(1) Prohibited Testimony or Other Evidence. During an inquiry
into the validity of a verdict or indictment, a juror may not
testify about any statement made or incident that occurred
during the jury’s deliberations; the effect of anything on that
juror’s or another juror’s vote; or any juror’s mental processes
concerning the verdict or indictment. The court may not re-
ceive a juror’s affidavit or evidence of a juror’s statement on
these matters.

(2) Exceptions. A juror may testify about whether:
(A) extraneous prejudicial information was improperly
brought to the jury’s attention;
(B) an outside influence was improperly brought to bear
on any juror; or
(C) a mistake was made in entering the verdict on the
verdict form.
