Story highlights Comedian Louis C.K. told his followers not to vote for Donald Trump in a postscript to a Saturday email

"It was funny for a little while," he wrote. "But the guy is Hitler."

In a postscript to a Saturday email about the latest episode of his web series "Horace and Pete," the comedian asked fans and readers to "please stop it with voting for Trump."

C.K. said he was "not advocating for Hillary (Clinton) or Bernie (Sanders)," and that he would indeed welcome a "good smart conservative" to take on the eventual Democratic nominee. But, he added, "Trump is not that. He's an insane bigot. He is dangerous."
