Just to be precise, if they invoke the 25th Amendment, that does NOT remove him from the Office of President. He will still be President. All it does is transfer the powers and duties of the President to the Vice President as Acting President. That is explicitly stated in the amendment. Therefore, Harris would NOT become President, and would NOT be the first woman President.
Even if Biden were to dispute it and reclaim the powers and duties of the Office of President, and the dispute devolved on Congress, and Congress sided with Harris and the Cabinet, he would still be President.
In other words, there is absolutely no way, under the 25th Amendment, that Biden can be removed from the Office of President. He can simply be deprived of the powers and duties of the Office. He could keep sending letters to Congress asserting that he is capable of carrying out the powers and duties of his office, and Congress could, at some point, give the powers and duties back to him. At least until January 20, 2025.
That is true but in the last seven days I think everyone knows Biden cannot remain in a position of authority. That will be Harris and that is how she will show up at the convention.
Thank you for this information.
I suspect it is not well known.
