Donald Trump's rise in the Republican Party seemed like the perfect fodder for former Daily Show host Jon Stewart. But Stewart, who retired last year from the show, has for the most part remained silent about the billionaire's rise in presidential politics.

Until now.

"I'm not a constitutional scholar, so I can't necessarily say, but are you eligible to run if you are a man-baby or a baby-man? I don't know," Stewart said at an event hosted by the University of Chicago's Institute of Politics on Monday. "But he is a man-baby. He has the physical countenance of a man and a baby's temperament and hands."

Stewart went on, calling Trump "an unrepentant, narcissistic asshole." (The comments start at around 8:05 in the video above.)

"He is a man-baby. He has the physical countenance of a man and a baby's temperament and hands."

Stewart argued that Trump's criticism that America is now weak and sensitive due to political correctness is ridiculous, considering Trump has proven to be so thin-skinned himself.

"Donald Trump couldn't handle us [The Daily Show] making a joke about him," Stewart said. "Graydon Carter did a joke about Donald Trump's hands 25 years ago. He's still not fucking over it." He added, "The idea being that, Muslims, hey man, all he's saying is they're evil and shouldn't be allowed in this country — he's just telling it like it is. But god forbid you say happy holidays in December; it's fucking war. So who is it who's exactly sensitive here?"

As Politico reported, Stewart also mocked Trump's campaign slogan: "When was America great? What is this time that he speaks of? '81 to '82? Like what are we talking about? And who took your country away from you?"

Stewart, however, didn't have very nice words for Hillary Clinton, saying she's "a very bright woman without the courage of her convictions, because I'm not even sure what they are." He clarified, though, that he prefers Clinton to Trump.

But that came with a very big caveat: "At this point, I would vote for Mr. T over Donald Trump."
