You have absolutely no idea how American jurisprudence works, do you?
Yes, all politicians have criminal immunity for EVERYTHING they do in office. Politicians are the ones who made the laws! 😥
Impeachment?? That is a trivial function designated to the House of Representatives.
Impeachment is just disparagement of one's character or conduct. Bill Clinton was Impeached, too. Doesn't mean anything. That's why MSM media keeps grinding on it do dummies think it matters! Impeachment is a political process, not a crime.
TREASON and SEDITION are the only crimes mentioned in the Constitution and the penalty is Death.
