To be honest, what could congress even do given what the supreme court has said? If Trump went full Hitler and decided to burn down the Capitol and have everyone in it killed who doesn't do his bidding, he couldn't even be held accountable by them in theory.
Yeah, "theoretically" is doing a lot of work there. Removal requires a 2/3 majority of the Senate, which is absolutely neverfuckinghappening in a 2-party system.
