The 25th Amendment requires a two-thirds vote in both Houses of Congress.

No, that's not true. Read it. It only requires two-thirds vote in both Houses of Congress if the President contests it, AND the Vice President and the Cabinet send another letter within 4 days to Congress saying "no, really, he can't do the job."

See Post #23. If the President contests a challenge to his authority under the 25th Amendment, then he basically eliminates the challenge by saying: “Hey, I’m alive!”
