Colbert, on his show Wednesday, discussed the fallout from a Trump joke two days earlier that prompted calls to fire him and boycott the CBS “Late Show” advertisers. He said he didn’t regret insulting the president, but that “I would change a few words that were cruder than they needed to be.” He made a reference to the male anatomy when he said of Trump Monday: “The only thing your mouth is good for is being Vladimir Putin’s c— holster.”
