UPDATE 10 PM: Michele Bachmann has received an apology from NBC over the song choice flap during her appearance on the network’s Late Night With Jimmy Fallon on Monday when the show’s house band performed the 1985 Fishbone song Lyin’ Ass Bitch while she was walking out on stage. The apology was made in a personal letter from NBC’s VP late night Doug Vaughan. According to Bachmann’s spokeswoman Alice Stewart cited by the AP, Vaughan wrote that the incident was “not only unfortunate but also unacceptable.” She said Vaughn offered his sincerest apologies and said the band had been “severely reprimanded.”

PREVIOUS 11 AM: The controversy over Late Night With Jimmy Fallon‘s choice of the 1985 Fishbone song Lyin’ Ass Bitch as intro music for guest Michele Bachmann shows no signs of subsiding. Conservative bloggers started the campaign on Tuesday morning, right after the show aired Monday night. Last night, Fallon apologized to the presidential candidate over the phone and via Twitter. “I’m honored that @michelebachmann was on our show yesterday and I’m so sorry about the intro mess,” Fallon wrote on Twitter. “I really hope she comes back.” Appearing on Fox News Channel’s America’s Newsroom this morning, Bachmann said that she accepts the comedian’s apology but insisted that the network that aired the broadcast, NBC, should apologize too. “If that had been Michelle Obama, who’d come out on the stage, and if that song had been played for Michelle Obama, I have no doubt that NBC would have apologized to her and likely they would have fired the drummer, or at least suspended him,” Bachmann said. “None of that happened from NBC. And this is clearly a form of bias on the part of the Hollywood entertainment elite, but it’s also, I think, sexism as well. This wouldn’t be tolerated if this was Michelle Obama; it shouldn’t be tolerated if it’s a conservative woman either.” So far, the only disciplinary measure toward Questlove, the drummer of Late Night‘s house band The Roots reportedly responsible for the song choice, came in a form of a tweet from Fallon yesterday, “?uestLove is grounded.” Bachmann on Tuesday received support from an unlikely ally, Democratic Congresswoman Nita Lowey. “The choice of song to introduce Michele Bachmann on Late Night With Jimmy Fallon last night was insulting and inappropriate,” she said in a statement. “I do not share Michele Bachmann’s politics, but she deserves to be treated with respect. No female politician — and no woman — should be subjected to sexist and offensive innuendo like she was last night. The Roots, Jimmy Fallon, and NBC should apologize.”
