If there is any doubt about who has the most Constitutional authority, Congress has the power to impeach and remove the President and anyone else in the Executive Branch; but the President cannot remove any Member of Congress or anyone else in the Legislative Branch. And by a two-thirds vote in both houses, Congress can over-ride a Presidential veto of any bill, thereby making that bill into a law, which the President must enforce, even if he disagrees with it. And if the President deliberately refuses to enforce a law he doesn't like, then that refusal becomes a "high crime or misdemeanor" which justifies his impeachment and removal from office. Finally, if the President should be so foolish as to try to order the Military to violate a Law of The United States, the Military is obligated to disobey the President and follow the Law . So in the event of a showdown, a unified Congress trumps the President every time.
