Fox News' co-host of "The Five" Bob Beckel has called on CBS to apologize for an episode of "The Amazing Race” set in Hanoi, Vietnam. In the episode, contestants go to a B-52 Memorial, which is the wreckage of an American bomber plane shot down during the Vietnam War, to find the next clue in their televised round-the-world journey. "Do you realize, CBS, there were four Americans that went down with that plane?" Beckel said on "The Five" Thursday. "Two of them died."
