Trump was literally impeached over causing an insurrection. What more proof do you need?
Even the leftists on Morning Joe this morning were saying they hope the Supreme Court issues a 9-0 overturning of Colorado's decision because they know they effed up.
Impeachment is a political procedure that isn't necessarily about finding facts or proof of anything.
I'll have to disagree about impeachment. More accurate to say it has become a political procedure. It serves a very real Constitutional function to remove crooks or traitors from office.
There shouldn't be a sort of handoff where House members accusing a President of the opposite political party of an offense is considered sufficient grounds for a court of law to find them guilty of that offense.
It might be a whole different deal if Colorado has actually discovered damning new evidence that the January 6th Committee didn't have access to. If that damning new evidence were available I'd think there would be new calls on a broader scale for Trump to be criminally charged for insurrection. But that hasn't happened.
