A Fox Business Network host apologized to Sen. John McCain's family Thursday after a guest on his show made derisive comments about Sen. John McCain's time as a prisoner of war.

Fox Business Network host Charles Payne apologized for failing to intervene when military analyst Thomas McInerney referred to McCain as "Songbird John." McInerney made the comments in a conversation about the enhanced interrogation practices that took place in the post-9/11 era, in light of the nomination of Gina Haspel for CIA director. Haspel testified about that dark chapter in CIA history in her confirmation hearing on Capitol Hill Wednesday, and pledged that such practices would not take place under her leadership.

"Well she can't use it anymore because we have determined, the Congress, that it's not legal," McInerney said of the interrogation methods. "The fact is, John McCain, it worked on John. That's why they call him 'Songbird John.' The fact is, those methods can work and they're effective, as former Vice President (Dick) Cheney said. And if we have to use them to save a million American lives, we will do whatever we have to."

McCain was tortured during his years as a POW in Vietnam. McInerney is a retired U.S. Air Force Lt. General who also served in the Vietnam War.

Payne took to Twitter after the segment aired, expressing regret that he didn't intervene in the military analyst's comments. He said he didn't do so because the control room was talking to him at the time through his earpiece and he didn't catch the comment.

"As a proud military veteran and son of a Vietnam vet, these words neither reflect my or the network's feelings about Senator McCain, or his remarkable service and sacrifice to this country," Payne wrote.

My Apology to Senator McCain and his Family

“This morning on a show I was hosting, a guest made a very false and derogatory remark about Senator John McCain. At the time, I had the control room in my ear telling me to wrap the segment, and did not hear the comment. — Charles V Payne (@cvpayne) May 10, 2018

I regret I did not catch this remark, as it should have been challenged. As a proud military veteran and son of a Vietnam Vet these words neither reflect my or the network’s feelings about Senator McCain, or his remarkable service and sacrifice to this country.”

McCain is now home in Arizona battling brain cancer.

During the presidential campaign, President Trump blasted McCain for being captured.

"He's not a war hero," Mr. Trump said in Iowa in July 2015. "He was a war hero because he was captured. I like people who weren't captured."

At the time, pundits suggested it could be the end of his presidential bid, but Mr. Trump went on to win the White House 16 months later.
