Doesn’t matter. Once you are impeached you are forbidden, forbade and illegally in a position in the US where you are paid, reap any benefit, etc. BUT...He’ a Democrat so the Constitution doesn’t matter.
Rules and laws are ONLY for GOPers ( especially Trump and us ) have to obey...claim the damned lefties. :-(
Only if someone is convicted by the Senate. Impeachment is just an indictment.
