If Mr Trump were demented or otherwise unfit for office I think his entire cabinet would have to vote unanimoously to remove him. An unlikely event perhaps. But I'm not very familiar with the US Constitution so maybe I'm not right.
“The 25th Amendment provides mechanisms to remove a president, primarily through Section 4, allowing the Vice President and Cabinet to declare a president unable to serve, or Section 1, where the VP immediately assumes the presidency if the president dies, resigns, or is removed via impeachment, which is part of the original Constitution (Article II, Section 4) and requires House impeachment and Senate conviction.”
Vance would initiate this if he was sure of success, he is ruthless enough and has been a critic of Trump in the past.
