He'd be crazy if he did, afs. In my opinion, he's having his best two weeks as President. He's finally selling himself as a centrist, so to comment on this (either way) would not be in his best interest. That's politics.
Not just that, but let's use a classic example from 1970:
Nixon's remarks were meant to criticize what he perceived as a tendency of the media to glorify criminals, and the White House quickly issued a statement denying any intent to prejudice the case. Nevertheless, Manson's defense, arguing that such a statement by the president made a fair trial impossible, motioned for a mistrial and demanded that the charges against him be dropped. Judge Older denied the motion.
The next day in court, Manson stood and displayed a newspaper with the headline, "Manson Guilty, Nixon Declares." Judge Older questioned the jurors about their reaction to the headline. Satisfied that they would remain impartial, he ordered the trial to resume and sentenced Atkins' attorney, Daye Shinn, to three nights in jail for leaving the newspaper within Manson's reach.
