Fire and Fury author Michael Wolff spoke out on Sunday about the White House staffs alleged concerns about President Donald Trump s fitness, saying that discussions on enacting a constitutional amendment to replace the president are alive every day in the White House.

Its not unreasonable to say this is 25th Amendment kind of stuff, Wolff told NBCs Chuck Todd on Meet the Press while discussing the interviews he says he had with West Wing officials that were published in his explosive new book.

The 25th Amendment allows the vice president to take over the position of president if the president is unable to do his job.
