On Tuesday night's episode of The Late Show, the CBS late night talk show had stand-up comedian Louis C.K. on the set to promote his new special on Netflix.
One of the world's most popular comics started off by expressing his regret at comments he had made about Trump past year, but then proceeded to say far, far worse. The comedian expressed, "I regret saying it - it doesn't mean it's not true".
Since then he has remained relatively quiet on the matter, but during an appearance on The Late Show with Stephen Colbert he couldn't hold his tongue.

"I thought be was some new kind of evil, but he's just a lying sack of shit". "It's just simple. It's simpler than I thought".

"Look if you voted, that's the guy he lied to", he said. He likes it. He goes, 'It wasn't even true. They just lie. They like it. News. Implying that the President belongs in the highest category of liars, Louis then proceeded to question the validity of Donald Trump's name.
