Va. Code § 19.2-262.01
In any criminal case, the court and counsel for either party shall have the right to examine under oath any person who is called as a juror therein and shall have the right to ask such person or juror directly any relevant question to ascertain whether the juror can sit impartially in either the guilt or sentencing phase of the case. Such questions may include whether the person or juror is related to either party, has any interest in the cause, has expressed or formed any opinion, or is sensible of any bias or prejudice therein. The court and counsel for either party may inform any such person or juror as to the potential range of punishment to ascertain if the person or juror can sit impartially in the sentencing phase of the case. The party objecting to any juror may introduce competent evidence in support of the objection, and if it appears to the court that the juror does not stand indifferent in the cause, another shall be drawn or called and placed in his stead for the trial of that case.
A juror, knowing anything relative to the fact in issue, shall disclose the same in open court.
