HBO’s “Real Time” host Bill Maher criticized Republican presidential candidate Ben Carson for comments he made about President Obama, who is “a centrist president” on Friday.

Maher said, “Ben Carson got in today. Ben Carson has said, today he said Obama ‘reminds you of a psychopath.’ Now when you use, when a guy uses the word ‘psychopath’ about a centrist president” before stammering as a way of showing how shocked he was at the comment. Maher later dubbed Carson “a smart, stupid person.”

ESPN commentator Will Cain and MSNBC host Alex Wagner did agree that Carson said “admittedly stupid things,” and that he shouldn’t be considered a serious candidate for president.
