Can’t Trump fire Pence for insubordination if Pence refuses to take his calls? It was the press at Biden’s “press conference” that ask if he was going to invite Pence to the inauguration.
There is no provision in the Constitution for the president to fire the VP. And even if Trump could fire Pence, considering the short leash Trump has in the current political climate, do you really really think Trump would be allowed to stay in office for the last 10 days of his term? He would be impeached and convicted in record time.
