Donald Trump has launched a staunch defence of his mental capacity, claiming he is "like, really smart" and "a very stable genius".
In an extraordinary series of tweets, the US President attacked what he described as the "fake news mainstream media" and claimed the investigation into Russian collusion in his 2016 election campaign was a "total hoax on the American public."
It comes just a day after a new tell-all book renewed the world's focus on the former real estate mogul's mental health, with the author claiming he was unfit to lead.
Here are Mr Trump's tweets in full:
"Now that Russian collusion, after one year of intense study, has proven to be a total hoax on the American public, the Democrats and their lapdogs, the Fake News Mainstream Media, are taking out the old Ronald Reagan playbook and screaming mental stability and intelligence.....
"....Actually, throughout my life, my two greatest assets have been mental stability and being, like, really smart.
"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!"
