President Trump, in an extraordinary public statement, pushed back against charges of mental instability and declared himself a genius. "Actually, throughout my life, my two greatest assets have been mental stability and being, like, really smart," he wrote on Twitter.

Trump's mental fitness was called into question by Michael Wolff's new book "Fire and Fury" and instantly exploded into a topic of global interest and debate.

Be smart: Trump felt he had to publicly reiterate that he is mentally stable enough to be president. He even reminded his followers of his career trajectory as a way to try to prove that point: "Crooked Hillary Clinton also played these cards very hard and, as everyone knows, went down in flames. I went from VERY successful businessman, to top T.V. Star ... to President of the United States (on my first try). I think that would qualify as not smart, but genius....and a very stable genius at that!"
