@Meyerweb and he'd be back in power within the hour most likely.
"when the President transmits to the President pro tempore of the Senate and the Speaker of the House of Representatives his written declaration that no inability exists, he shall resume the powers and duties of his office unless the Vice President and a majority of either the principal officers of the executive department or of such other body as Congress may by law provide, transmit within four days to the President pro tempore of the Senate and the Speaker of the House of Representatives their written declaration that the President is unable to discharge the powers and duties of his office.
Thereupon CONGRESS SHALL DECIDE THE ISSUE"
emphasis mine. Same congress that wont impeach and convict him isnt going to do squat
