You've probably already seen President Donald Trump's latest eye-roll-inducing tweets, claiming to be "like, really smart" and a "very stable genius" in response to claims that White House employees were worried about his "mental powers".


The claims were published in Michael Wolff's dramatic new book: Fire and Fury: Inside the Trump White House. 


The president fought back using his favorite medium: Twitter.

Many Twitter users were left bemused by Trump's tweets, while others took another chance to poke fun at him.

Trump was later asked by reporters why he felt the need to defend himself, replying that it was because he went to "the best colleges or college" and "made billions and billions of dollars". Okay.
