Louis C.K.: Trump is a “Gross Crook Dirty Rotten Lying Sack of Sh*t.” [VIDEO]

Last night on the Late Show with Stephen Colbert Louis C.K. said the he regrets sending a harsh letter to fans last year about then-candidate Donald Trump.

β€œI guess he’s not as profound as I thought he was,” the comedian said of Trump during an appearance on β€œThe Late Show” Tuesday night. β€œI thought he was some new kind of evil but he’s just a lying sack of shit … He’s just a gross crook dirty rotten lying sack of shit.”

A year ago, C.K. emailed a letter to fans urging them to stop supporting Trump’s candidacy.

β€œPlease stop it with voting for Trump. It was funny for a little while. But the guy is Hitler. And by that I mean that we are being Germany in the β€˜30s,” C.K. wrote.

The letter landed him on the cover of the New York Daily News alongside Trump, which C.K. said was not his intention.

Before the November election, C.K. made his support for Hillary Clinton clear. During an appearance on β€œConan” last year, he said, β€œIf you vote for Hillary you’re a grown-up. If you vote for Trump you’re a sucker.”
