Chris Cuomo erupts at heckler

A heated exchange between CNN anchor Chris Cuomo and a heckler was caught on video. Cuomo confronted the heckler after he called the anchor "Fredo," a reference to the hapless character of Fredo Corleone in the 1972 film “The Godfather.” President Trump responded to the viral video on Twitter, suggesting a “red flag” for Chris Cuomo. A "red flag" means putting the anchor on a list of people who are not allowed to own guns.
