I’ve thought about that. But a president can issue pardons on his last day in office. At that point, he is essentially unimpeachable, and Congress has no remedy.
He can still be impeached and perhaps that’s why Presidents generally wait until their last few days in office.
Somebody needs to have the irrevocable and irrefutable right to pardon. Why not the President? Anybody else and it’s subject to the whims of politics.
