A video has gone viral showing CNN anchor Chris Cuomo in an altercation with a man who called him “Fredo” -- which Cuomo says is as offensive to Italians and Italian-Americans as the N-word is to African-Americans.

The New York Post reports Cuomo appeared to angrily clash with a man who called him Fredo, as in Vito Corleone’s son Fredo from “The Godfather." The acclaimed 1972 movie follows Vito (Marlon Brando) transferring power over the mafia family to his son Michael (Al Pacino) to the dismay of Michael’s weaker brother Fredo (John Cazale), who betrays him.

“Punk ass bitches from the right call me ‘Fredo.’ My name is Chris Cuomo, I’m an anchor on CNN,” Cuomo tells the man in a video shared on social media Monday night. “Fredo is from the ‘Godfather,’ he was a weak brother and the use of it to an Italian is disparaging."

Cuomo, the brother of New York Gov. Andrew Cuomo, says the name “Fredo” is “like the N-word to us.”

“Don’t f–ing insult me like that,” he continues. “You call me ‘Fredo’ it’s like I call you punk b–ch, you like that?”

The man tells Cuomo he thought Cuomo’s name was really “Fredo.”

“You did not think that," Cuomo responds. "I’ll f---ing throw you down these stairs like a f---ing punk… you’re gonna call me Fredo, take a f---ing swing? I’ll f---ing wreck your s---.”

According to the Post, the clip was filmed Sunday in an encounter at a bar in Shelter Island, N.Y. and sent to a right-wing website and blog before being shared on Twitter. “That’s the Point with Brandon” host Brandon Recor told The Washington Post that the man who sent it to him said the confrontation began when he went up to Cuomo to ask for a picture.

“Chris Cuomo defended himself when he was verbally attacked with the use of an ethnic slur in an orchestrated setup. We completely support him," CNN spokesman Matt Dornic said in a statement on Twitter.

Others who defended Cuomo include Fox News host Sean Hannity, who said the CNN rival is the one who “deserves the apology.”

Cuomo, who hosts “Prime Time” weeknights on CNN, has not addressed the incident on-air. On Twitter, he said he’s on vacation this week after celebrating his 49th birthday and will return on Monday.
