 This deals with the executive branch. So they just can't call something up. What would happen with the 25th Amendment is it starts with the vice president. Kamala Harris would have to say, I think he's out of it. And then they would have to have 15 out of the 15 cabinet secretaries. A majority of them say, yes, we agree. The president could then say, no, I'm fine. And only then could you go to the Congress and you need a two thirds vote to override what the president has said.
