I actually agree with him here. The trial should be after the election.
Why though? If he is guilty in this, don't the people have a right to know that before the election? Everyone seems to think it's important that Hillary be held accountable beforehand, so why not Trump?
If it's a jury trial, it will be biased by jurors who secretly want to swing the election one way or another. BTW this is why congress impeaches and convicts the president rather than a citizen jury, so the politics of the trial is all out in the open for the people to approve (1868) or disapprove (1998) of.
Then Trump can request a bench trial. I doubt the judge will object.
Actually in a civil case the right to demand jury by trial belongs to either party, and the plaintiffs surely will.
