It also would be a bit inappropriate I think, given that it’s his Executive branch that’s prosecuting him in a number of these cases. Even though it sure seems like he’s maintaining distance from the Justice dept and allowing them their independence (unlike his predecessor), the optics of a President using the Justice dept to attack a political opponent, then using it in political campaign attacks would look kinda bad. The Georgia case though I think would be fair game, but better to just let that case speak for itself and not potentially influence it.
