“It was a misunderstanding,” the “30 Rock” star told Letterman. “It became a big, big misunderstanding.”

In June, Kevin Rogers, an audience member of the Nashville show, posted a Facebook note detailing why he walked out of the comedian’s act. During the routine, Morgan said being gay is a choice and that he would stab his son to death if his child came out to him, according to Rogers. Morgan publicly apologized several times.

“I apologized because people came to the show and they paid money and they got upset about it,” Morgan said Monday. “That wasn’t my intention to hurt anybody with my humor. That’s not my goal.”

Morgan said he could not recall exactly what he said at the show.

“I'm 43 years old; why would I become homophobic now?” he asked. “We forgot about [‘Saturday Night Live’ character] Brian Fellow?”
