President Donald Trump, coming off a week of heightened scrutiny over his mental health, sought to put the topic to rest on Saturday by declaring himself extraordinarily intelligent and undeniably right in the head. The series of three tweets came early Saturday from the frozen woods of Maryland, where Trump is huddling with Republican lawmakers at Camp David. Trump alleged that his critics were "screaming mental stability and intelligence" as compensation for a Russia investigation that has, thus far, failed to produce evidence that he or his associates colluded with Moscow. Citing his unlikely trajectory from businessman to reality television star to US president, Trump declared himself "like, really smart.” "I think that would qualify as not smart, but genius....and a very stable genius at that!" he wrote. Like many of Trump's tweets, the messages caught some aides off guard. By midday, chief of staff John Kelly hadn't yet seen or heard of them, and offered only a clipped "OK" when read them by reporters. Later, during a news conference alongside the Republican leaders, Trump offered a fulsome accounting of his credentials in explaining why he sent the tweets. "Only because I went to the best colleges, the best college, I had a situation where I was a very excellent student, came out, made billions and billions of dollars, became one of the top business-people, went to television for 10 years and was a tremendous success, as you probably have heard, ran for president one time and won," he said.
