In an interview that will air on Nightline tonight, former Presidential and Vice Presidential candidate John Edwards tells ABC's Bob Woodruff that he did have an affair with Rielle Hunter, as was first alleged by the National Enquirer in October 2007. Edwards repeatedly denied the affair during his Presidential campaign.
In the Nightline interview, Edwards confirms that he was visiting Hunter at the Beverly Hilton when he was chased by Enquirer reporters last month. But he denies the further allegations that he fathered Hunter's daughter, saying the affair ended too soon for that to be possible. Former Edwards campaign aide Andrew Young has said he is the child's father.
Edwards emphasized to ABC that the affair began when his wife Elizabeth's cancer was in remission. He says Elizabeth has known about the affair since 2006.
It's safe to say this revelation ruins any chance of Edwards being selected as Barack Obama's running mate.
