Just when he thought he was out, they pulled him back in.

Cable news host Chris Cuomo apologized Tuesday for his viral, profanity-laced rant against a man who called him “Fredo,” saying that agitators are constantly “baiting” him, but that he should know better than to bite.

“Appreciate all the support but – truth is I should be better than the guys baiting me,” tweeted Cuomo, whose brother is New York Gov. Andrew Cuomo and father was the late three-term Gov. Mario Cuomo.

“This happens all the time these days. Often in front of my family,” he wrote. “But there is a lesson: no need to add to the ugliness; I should be better than what I oppose.”

The CNN anchor was caught on video laying into an unidentified man who taunted him in public as “Fredo,” in a reference to Fredo Corleone, the ineffectual middle son of Don Vito Corleone in “The Godfather.”

“Punk-ass bitches from the right call me ‘Fredo,'” fumed Cuomo, 49. “He was a weak brother and the use of it to an Italian is disparaging.”

“I’ll f–king throw you down these stairs like a f–king punk. … You’re gonna call me Fredo, take a f–king swing,” railed Cuomo in the clip, purportedly filmed Sunday on Shelter Island. “I’ll f–king wreck your s–t.”

In his fury, it evidently slipped Cuomo’s mind that he once referred to himself as Fredo in a 2010 radio interview with Curtis Sliwa.

It’s an assessment with which President Trump agrees, as he tweeted Tuesday, “I thought Chris was Fredo also. The truth hurts.”

CNN stood by its anchor, with a spokesperson telling The Post: “Chris Cuomo defended himself when he was verbally attacked with the use of an ethnic slur in an orchestrated setup. We completely support him.”
