WATCH: #FireColbert Doesn’t Stop Stephen Colbert From Insulting Donald Trump

Stephen Colbert brushed aside calls for his firing on Tuesday night be continuing his rants against President Donald Trump. Colbert was criticized after a joke on Monday about Trump’s relationship with Vladimir Putin that many saw as “homophobic.”

During the 12-minute monologue on Monday, seen above, Colbert ran down a long list of insults CBS News’ John Dickerson would have been too scared to deliver after Trump walked out of Dickerson’s interview early when wiretapping questions came up.

“Sir, you attract more skinheads than free Rogaine,” Colbert told Trump. “You have more people marching against you than cancer. You talk like a sign language gorilla that got hit in the head. In fact, the only thing your mouth is good for is being Vladimir Putin’s cock holster.” That last phrase is considered a homophobic slur by many.

Back in 2014, Anderson Cooper explained to Howard Stern that jokes about sexual acts between men are considered insulting because you are talking about it as if it’s “the worst thing you can possibly think of” and devalues that relationship.

“The worst thing you can possibly think of to say, which is what this situation was, to talk about a sexual act between two guys as being the worst thing you can possibly think of,” Cooper said in 2014 after Alec Baldwin used the term “cocksucker.” “That seems to indicate— but I never said [Baldwin] was homophobic. I have no idea what’s in his head.”

Colbert has spent much of the past few months making fun of Trump, returning to the political humor that dominated his old show, The Colbert Report. He continued to mock the president on Tuesday’s show, joking about a new U.S. Constitution written by Trump and suggested that Trump wants to change the First Amendment after White House Chief of Staff Reince Priebus said the Trump administration is looking into a Constitutional amendment to change libel laws.

In another segment on Monday, Colbert edited Dickerson’s Face the Nation interview to make it look like he interviewed Trump himself.

CBS hasn’t commented on calls for Colbert to be fired.
