Again I ask, how do we “remove” a President who is by definition not the President? The fraud precedes and deligitimizes everything subsequent. We are currently operating without a President, because the office is preeminently defined by the authority invested by those who elect him, and that authority simply does not exist. It never has. He a pretender. No need to act or think otherwise.
And again, I answer Article II Section 4.
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.
Perpetrating voter fraud is a High Crime.
Congress had the opportunity to challenge the Electoral votes cast by the individual states. The Republicans were on their way to delaying the count by challenging the Electoral votes from all of these contested states, and were going to do force a joint Congressional investigation into voting irregularities when the Capitol was breached. After they reconvened, the Republicans lost their nerve.
Congress voted to accept the Electoral Votes, declared Biden and Harris the winners, and Biden and Harris were sworn in. All as the Constitution stipulates.
Once the oath has been administered, that person IS the President. Any fraud discovered afterwards does not nullify Congress' actions. It provides grounds for Congress to undo their mistake via Impeachment and removal from office.
I'm sorry you don't like how our founding fathers wrote the Constitution, but that doesn't change the facts.
Biden may not be the President in your eyes, and he certainly isn't the President in my eyes, but in the eyes of the Constitution, he is the President.
