They can’t.
Waller comments on that here:
“The Constitution defines who is subject to impeachment (Article II, section 4). It stipulates, “The President, Vice President and all civil Officers of the United States, shall be removed from Office on Impeachment for, and Conviction of, Treason, Bribery, or other high Crimes and Misdemeanors.” The Senate must vote separately to bar an impeached official from office. That vote, unlike the vote to convict, requires a simple majority. But that vote is not in order until after the Senate has voted to convict the official based on the articles of impeachment. The Senate cannot remove someone from office if they are not in that office. And absent a conviction vote, the Senate cannot bar someone from holding future office. The consequences of giving Congress this power would be to allow it to bar private citizens from holding office preemptively.”
So they cannot remove Trump or ban him from future office.
Meaning the impeachment is a meaningless exercise, which will just serve to enrage us & many other Americans.
They are stupid.
plan B is to arrest him for inciting a riot at 12:01pm on Jan 20
