In the 107 seconds of the video, Mr. Cuomo uses forms of the f-word 24 times and uses the s-word meaning "excrement" five times.
The footage starts with an agitated Cuomo erupting into an expletive-ridden rant while accusing the man of hurling an ethnic slur at him.
"Are you Italian?" Cuomo asks someone out of the frame. "I'll f-- throw you down these stairs like a f-- punk".
Chris was in NY Sunday when a guy approached him and called him "Fredo". the insulting name of a character in "The Godfather". a name that connotes weakness.
"If you've got something to say about what I do on television, then say it, but you don't have to call me a f--in' insult", Cuomo continued.
If he calls Chris Cuomo that again, he could be sleeping with the fishes. Maybe that last part is why Cuomo took things a bit further and told the man that "Fredo" was like the N-word for Italians. "Own what you said".
Hannity, a long-time critic of CNN, defended Cuomo after he was filmed threatening to beat up a man-believed to be Donald Trump supporter-after he called him a "Fredo", saying his fellow news host has "zero to apologize for". Cuomo then warns that the two will have "a problem".
"Hey @ChrisCuomo, take it from me, "Fredo" isn't the N word for Italians, it just means you're the dumb brother", Trump. "We completely support him", wrote Matt Dornic, a CNN vice president and spokesman.
At one point, while the shaky camera was moving around, someone who sure sounded like Cuomo could be heard egging someone else on, saying, "Take a swing!" Cuomo - also the son and brother of powerful men, former NY governor Mario and current governor Andrew Cuomo, respectively ― did not push back.
Others on Twitter pointed out that CNN anchor Jake Tapper depicted Trump Jr.as Fredo in his political cartoon segment back in December and a CNN guest called Rep. Devin Nunes, R-Calif., the "Fredo of the Republican Party" in March.
Mr. Dornic was replying to Donald Trump Jr., who had retweeted the video and said he assumed the network wouldn't comment because it's not a real news organization. Fredo is the fictional son of mob boss Vito Corleone and considered the weakest of his brothers.
