Theoretical question: what happens if he doesn’t do what the courts order, and the congress is too afraid to impeach him?
He's already defying multiple court orders and the Congress is not impeaching him. Oh, some of the politicians are introducing articles of impeachment, but you can see quite clearly that this won't go anywhere.
This is no longer a representative democracy, but an autocracy.
I.e. when militias take up arms by themselves, perhaps a court would “authorize” their actions with something like this.
I don’t think any judge will voluntarily be the spark that ignites a civil war
