Colbert first brought up C.K.'s comments in a scathing March 2016 email for fans that likened Donald Trump to Hitler, a remark that the comedian later downplayed. "I don't take it back; I regret it. There's a difference," C.K. told Colbert.
Asked how his perception of Trump had changed, the comedian explained, "Now, I guess he's not as profound as I thought he was. I thought he was some new kind of evil. But he's just a lying sack of shit."
"Sometimes people lie. 'That guy lied, they found out he lied.' And then there's somebody who lies once in a while, can't quite stay inside the boundaries of truth, right? Somebody who lies sometimes. Then you have a liar, whose somebody who has a problem, they can't help it, they lie a lot. And then you have a lying sack of shit… They like it, he likes it… It's insane, he's just a gross, crook, dirty, lying sack of shit."
Colbert added that Trump was the living embodiment of lying, "I don't know what color his hair is. I don't know what color his skin is. I don't know how much money he has."
After teasing the one Trump voter in Colbert's Hillary-heavy audience, C.K. subtly chastised the millions of people who didn't use their vote on Election Day because they don't like waiting in lines or because they didn't like either candidate.
"Don't you want God to show up and say 'I was just kidding' about everything? I just wish that he would," C.K. said remorsefully about our current situation.
C.K., Number Four on Rolling Stone's Best Stand-Up Comics of All Time list, visited The Late Show to promote his new Netflix comedy special 2017, which premiered on the streaming service Tuesday, the first of two exclusive specials.
