 is the 25th Amendment. You know this. Specifically, Section 4. It's a process, of course, just like everything else up there, but it starts with the Vice President and a majority of the principal officers of the executive departments, essentially the Cabinet. And they submit a written declaration of the President, pro tem, of the Senate, and the Speaker of the House of Representatives. And this declaration states that the President's not able to discharge the duties of the office.
