or another juror’s vote; or any juror’s mental processes concerning the verdict or
indictment. The court may not receive a juror’s affidavit or evidence of a juror’s
statement on these matters.
(2) Exceptions. A juror may testify:
(A) about whether an outside influence was improperly brought to bear on any
juror; or
(B) to rebut a claim that the juror was not qualified to serve.
