Denver (AP) Barack Obama is striking back fiercely and swiftly at an ad linking him to a 1960s radical.
The ad is funded by one of the main supporters of the Swift Boat Veterans for Truth, which went after John Kerry in 2004. This ad questions Obama's ties to William Ayers, a founder of the radical Weather Underground organization that took credit for a series of
bombings four decades ago.
The two men once served together on the board of a charity in Chicago. And Obama chaired a school reform group of which Ayers was a founder. Ayers also hosted a meet-the-candidate event when Obama first sought public office.
Fox News and Cnn won't air the ad, but stations in four states already have.
Obama has put out a response ad, and the campaign may ask the Justice Department to intervene. It might also pressure advertisers on stations airing the anti-Obama commercial.
