I 'guess' that the defendant would have to file some sort of change of venue request...but where is that adjudicated?
From Wikipedia on the 6th Amendment:
Impartiality
The Sixth Amendment requires juries to be impartial. Impartiality has been interpreted as requiring individual jurors to be unbiased. At voir dire, each side may question potential jurors to determine any bias, and challenge them if the same is found; the court determines the validity of these challenges for cause. Defendants may not challenge a conviction because a challenge for cause was denied incorrectly if they had the opportunity to use peremptory challenges.
Venire of juries
Another factor in determining the impartiality of the jury is the nature of the panel, or venire, from which the jurors are selected. Venires must represent a fair cross-section of the community; the defendant may establish that the requirement was violated by showing that the allegedly excluded group is a "distinctive" one in the community, that the representation of such a group in venires is unreasonable and unfair in regard to the number of persons belonging to such a group, and that the under-representation is caused by a systematic exclusion in the selection process. Thus, in Taylor v. Louisiana, 419 U.S. 522 (1975), the Supreme Court invalidated a state law that exempted women who had not made a declaration of willingness to serve from jury service, while not doing the same for men.
Vicinage
Main article: Vicinage Clause
Article III, Section 2 of the Constitution requires defendants be tried by juries and in the state in which the crime was committed. The Sixth Amendment requires the jury to be selected from a judicial districts ascertained by statute. In Beavers v. Henkel, 194 U.S. 73 (1904), the Supreme Court ruled that the place where the offense is charged to have occurred determines a trial's location. Where multiple districts are alleged to have been locations of the crime, any of them may be chosen for the trial. In cases of offenses not committed in any state (for example, offenses committed at sea), the place of trial may be determined by the Congress
