Trlump pushes back over mental fitness, calls himself 'a very stable genius'

The president tweeted a defense against claims he is mentally unfit for office.

His defense of his capacity to serve as U.S. commander in chief comes after a new book, "Fire and Fury," reports that people around Trump, including top White House aides, question his intelligence and fitness for office.

Even as the federal investigation continues into alleged Russian interference in the 2016 election and possible collusion by Trump associates, the president tweeted that Democrats and the media are raising questions about his mental fitness because claims of "Russian collusion" have turned out to be "a total hoax."

While this is the first time Trump has directly engaged on the topic of his mental fitness amid new claims in the “Fire and Fury” book, the White House has forcefully denounced such questions as “disgraceful and laughable.”
