Bill O’Reilly tonight weighed in tonight after NBC News’ Brian Williams recanted a story about being in a helicopter that was forced down by RPG fire.

Williams has told the story multiple times, including on “The Late Show With David Letterman.”

“You go on ‘Letterman’ and you wanna please, you wanna be interesting, you wanna be fascinating, you wanna be cool […] he wants to be cool,” O’Reilly said. “That was the narrative that he invented for himself to be cool.”

Lauren Ashburn called on NBC News to reprimand Williams.

“This is the biggest slap in the face to veterans,” Ashburn said of the “war story lie.”

Howard Kurtz also weighed in, calling this “a huge credibility crisis.”
