Just goes to prove, on the LEFT a Crime is not required for removing a sitting President when they hate him. IMHO the GOP will jump on board - at least some of them like Flaky Flake and Juan McStain.
Impeachment does not depend on what the Law defines as crimes or misdemeanors. The phrase I the Constitution “High Crimes and Misdemeanors” is not defined and the Congress can define it any way the congress chooses. All that is required is sufficient votes to carry the impeachment. Anything at all can be adduced as the High Crime or Misdemeanor that elicits the impeachment including DJT’s hair which is at least a sartorial crime.
