Colbert uses Descartes to mock Trump: ‘I think, therefore I am, like, really smart'

Stephen Colbert late Monday mocked President TrumpDonald John TrumpAccuser says Trump should be afraid of the truth Woman behind pro-Trump Facebook page denies being influenced by Russians Shulkin says he has White House approval to root out 'subversion' at VA MORE for a tweet that he was a "stable genius" and "like, really smart."

During "The Late Show," Colbert said being "like, really smart" is not the same thing as "being really smart."

Colbert added that people who are mentally stable "generally don't announce it."

“We all know geniuses spend most of their time talking about how smart they are," Colbert joked.

"I believe it was René Descartes who said, ‘I think, therefore I am, like, really smart.’”

His comments come after Democrats and the media have raised questions about Trump's mental fitness for office in the wake of revelations from a new book detailing the first year of the Trump administration.

Trump over the weekend tweeted about his mental stability.

"Actually, throughout my life, my two greatest assets have been mental stability and being, like, really smart," Trump said.

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!"
Trump this past weekend told reporters he was an "excellent student" who went to "the best college" in seeking to explain why he called himself a "stable genius."
