In a tweet Monday morning, Senator John McCain, R-Ariz., voiced his support for the apology CBS published concerning a recent episode of “The Amazing Race” that took place in Vietnam. McCain, a former Navy pilot who spent five-and-a-half years in a Hanoi prison, is one of the most well-known Vietnam War veterans.

Parts of the March 17 episode angered many veterans after it showed an American B-52 bomber in Hanoi used as a prop and contestants learning a song with pro-communist lyrics, USA Today reports.

CBS issued an apology on its Facebook page on Sunday. In a 26-second video with a blue background and slides of white text being read out loud, the network acknowledged parts of the episode “were insensitive to a group that is very important to us” and apologized to veterans and their families.

“To CBS, I say, ‘Apology accepted,’” wrote James E. Koutz, American Legion national commander and a Vietnam War veteran, after the network’s statement. In an open letter published last week, Koutz denounced the show, calling it “The Amazing Gall” and demanding an apology.

John Hamilton, the commander-in-chief of Veterans of Foreign Wars, also accepted on Monday the CBS apology. Three days earlier, Hamilton said about the episode: “CBS reopened an old wound by failing to educate a viewership about a time in American history that continues to be misunderstood, misrepresented and stereotyped.”

But not all veterans see the CBS statement as an apology.

“Out of my unit, three of us came home,” Eugene Kemp, who identifies himself as a Vietnam veteran, wrote on the CBS Facebook page. “Sounded ‘canned’ to me.”

“This is no apology,” Leigh Hardy wrote. “An apology requires asking forgiveness and admitting you are wrong. Neither of which are found in this statement.”
