> Will they do this?
so the question is why?
The point about what they're legally allowed to do, and could do, is moot, if there's no will.
Judiciary is easy. They don't want to take drastic actions unless absolutely pushed. The entire idea is to be meticulous and try to avoid the political climate when making judgement. They are taking action but they havent taken their gloves off yet.
Congressional's reasons: your guess is as good as mine. Their majorities aren't that wide. moving 3 senators can affect policy, moving half the senators can get an impeachment trial. We'll see how things proceed there.
