In Case of the Removal of the President from Office, or of his Death, Resignation, or Inability to discharge the Powers and Duties of the said Office, the Same shall devolve on the Vice President, and the Congress may by Law provide for the Case of Removal, Death, Resignation or Inability, both of the President and Vice President, declaring what Officer shall then act as President, and such Officer shall act accordingly, until the Disability be removed, or a President shall be elected.

When the USS Caine, a fictional minesweeper in WWII, was in danger of foundering in a hurricane, the Executive Offer, with the encouragement of the Wardroom, relieved the CO and “saved” the ship. It was a clear-cut case of mutiny, and as such a Court Martial would be required to resolve the matter.

The interesting thing is that the movie itself, and specifically was in the minds of the commission that gathered to consider the words of what would become the 25th Amendment to the US Constitution.
Today you can buy a “25/45” T-shirt and you’ll hear Talking Heads debating the whole idea of how the 25th Amendment could be used to rid the country of the hated Trump. What was once considered a ridiculous idea has gained enough steam that Vice President Pence had to specifically deny that he had conversations with the Cabinet regarding the implementation of the 25th. In fact, many people still believe that he wrote the infamous New York Time Op-Ed as the opening shot of a 25th coup d’état.
The problem is that the 25th was never intended to get rid of a President because some part of the country doesn’t like the way he parts his hair…
