CNN is standing by anchor Chris Cuomo after a profanity-laced video of him threatening a heckler went viral Monday.

The "Cuomo Prime Time" host, 49, was captured during a heated exchange with an unidentified man who called him "Fredo," which Cuomo called a racist slur toward Italians, comparing it to the N-word.

"Punk (expletive) from the right call me 'Fredo.' My name is Chris Cuomo. I’m an anchor on CNN," the television host said during the NSFW video that was shared on Twitter.

The journalist explained that the "disparaging" term is from the 1972 film "The Godfather," referring to Fredo Corleone, who Cuomo said is "a weak brother."

As the conversation escalated, Cuomo added: "I’ll (expletive) ruin your (expletive). I’ll (expletive) throw you down these stairs like a (expletive) punk … you’re gonna call me Fredo, take a (expletive) swing?"

The footage was first shared by conservative media personality Brandon Straka on his YouTube channel, "That's the Point with Brandon." He claims the man Cuomo threatened is a Trump supporter who believed the anchor's real name was "Fredo."

In the footage, Cuomo shot down the claim, telling the heckler directly, "You did not think that. … Don't be a liar. You want to be a man, stand up like a man. … Own what you said."

CNN offered support for Cuomo following the video's release, claiming that the anchor was targeted in an "orchestrated setup."

"Chris Cuomo defended himself when he was verbally attacked with the use of an ethnic slur," CNN Vice President of Communications Matt Dornic tweeted. "We completely support him."

Even Fox News host Sean Hannity, who airs in the same time slot as Cuomo, backed the CNN personality.

"I say good for @ChrisCuomo," Hannity tweeted. "He’s out with his 9 year old daughter, and his wife, and this guy is being a jackass in front of his family. (In my honest opinion) Chris Cuomo has zero to apologize for. He deserves the apology."

Lawyer Michael Avenatti added, "Bravo to @seanhannity for calling what happened like it is."

Anthony Scaramucci, the former White House Communications Director, said he's "very proud of @ChrisCuomo." He added, "This happens all the time. It’s quite racist."

Others challenged Cuomo's claim that "Fredo" is a slur.

Donald Trump Jr. tweeted, "Hey @ChrisCuomo, take it from me, 'Fredo' isn’t the N word for Italians, it just means you’re the dumb brother."

Former Miss Ohio USA Madison Gesiotto said, "I am an Italian-American and 'Fredo' is honestly not the term that I would consider to be the most insulting against Italians."

Social media users also unearthed footage of political commentator Ana Navarro using the term on "Cuomo Prime Time" in January. In the clip, Cuomo did not acknowledge its usage.

"Weird, I don't recall him having an issue with Ana Navarro calling @DonaldJTrumpJr 'Fredo' ON HIS SHOW ON CNN," Caleb Hull tweeted.

"The View" co-host Meghan McCain did not take a side, but she did say that women would be held to a higher standard if they were in a similar situation.

"However you feel about Chris Cuomo’s behavior today, there’s not one woman in ALL of media who could be filmed in public on an obscenity filled tirade and be supported by their network and public the way he is right now. Men get to be tough and swear, women are 'unhinged,'" she tweeted.

Cuomo – who is the son of former New York Gov. Mario Cuomo, and brother to the current New York governor, Andrew Cuomo – has not publicly addressed the footage yet.
