I dunno but it looks like Wayne Madsen has his paws all over this.

I don’t think Wayne Madsen has much credibility, seems he is pretty controversial.
Section 4 would allow Vice President Biden, along with a majority of either ‘the principal officers of the executive departments,” the Cabinet or “such other body as Congress may by law provide,” to declare the President disabled by submitting a written declaration to the president of the Senate pro tem Senator Daniel Inouye (D-HI), and the Speaker of the House of Representatives, Representative Nancy Pelosi (D-CA). Under Section 3 of the 25th Amendment, Vice President Biden would become Acting President.
Man, if Pelosi realizes the power she would wield in this situation, she could exact her revenge against Obama big-time by helping to declare him mentally unfit for office.
Obama has every reason to feel paranoid.
