Because judges hold people in contempt of court, which can include fines or jail time. Even if POTUS is exempt from such penalties, other’s in the executive branch may not be, and don’t want to find out later they can be punished. The best option is for Congress to act to limit the jurisdiction of these courts, or require three judge panels to hear such cases to avoid the forum shopping for leftist Rat judges.
“Because judges hold people in contempt of court”
Understood though my argument means that we have another judge saying Trump is OK to do what he is doing, so even if the former judge claims contempt, the other pro trump judge can claim the opposite, and could even claim to hold that former judge in contempt
Trump can just hand out presidential pardons, like party favors.
We can play their petty political game.
