Stephen Colbert has come under fire on social media for a crude joke he made about President Donald Trump on Monday’s broadcast of The Late Show that some critics claimed was bigoted and homophobic.

While attempting to defend his CBS colleague John Dickerson, Colbert said Trump’s mouth is only “good for is being Vladimir Putin’s c*ck holster.”

Outraged by the remark, social media users quickly made the hashtag #FireColbert a top trending topic on Twitter Tuesday.

“Colbert’s homophobic rant was disgusting and we won’t tolerate this anti-LGBTQ behavior,” one user wrote.

“Liberals ruin the careers of conservatives all the time, so the #FireColbert campaign is just giving libs a taste of their own medicine,” argued another.

Some called Colbert a “homophobe” and a “bigot.”

Some social media users called for a boycott of CBS and the network’s advertisers.

Time for him to go. Total trash. I will boycott advertisers. #FireColbert — hank_1972 (@Hank_1972) May 3, 2017

German Lopez, a reporter for left-wing news outlet Vox, wrote that Colbert’s joke pointedly mocked gay people.

“In a setting in which Colbert is deliberately trying to find a way to insult Trump, it’s telling that he resorts to suggesting that Trump is engaging in sexual acts with another man. The suggestion is that the worst thing that could happen for these men is if they engaged in homosexual acts together, as if that devalues them as men or emasculates them.”

Colbert’s over-the-top late-night monologue also included fat jokes about President Trump.

“Mr. President, I love your presidency. I call it ‘Disgrace the Nation,'” he began. “You’re not the POTUS; you’re the ‘BLOTUS.’ You’re the glutton with the button. You’re a regular ‘Gorge Washington.’ You’re the ‘presi-dunce’ but you’re turning into a real ‘prick-tator.’”

“Sir, you attract more skinheads than free Rogaine,” Colbert continued. “You have more people marching against you than cancer. You talk like a sign-language gorilla that got hit in the head.”

Colbert did not address the firestorm surrounding his comments during Tuesday night’s episode of The Late Show, opting instead to continue to blast Trump and Putin.

The CBS host compared the president to author Stephen King, saying Trump just “makes things up.” He also aired a 30-second clip of Trump’s quotes taken out of context.

Colbert’s ratings have risen steadily since Inauguration Day. The CBS host has regularly beaten late-night rival Jimmy Fallon’s Tonight Show since January, though Fallon still usually leads in the adults 18-49 demographic.
