But Edwards, a former U.S. senator from North Carolina, told ABC News he isn't the father of Rielle Hunter's daughter and that he didn't love Hunter, a video producer he admitted having a 2006 sexual relationship with. He said he had ended the affair before Hunter's child was conceived. Andrew Young, who worked on the Edwards campaign, has said he is the father.

The Edwards interview was to air on "Nightline."

Edwards said he met Hunter in a New York bar. She worked for the campaign producing Web documentaries.

Edwards' wife, Elizabeth, announced during the presidential campaign that she had suffered a recurrence of breast cancer. Edwards told ABC News that at the time of the affair his wife's cancer was in remission.

Fred Baron, the financial chairman of the Edwards campaign, told NBC Friday he helped Young and Hunter financially. He said that included giving them money to allow Hunter to move out of North Carolina, where the National Enquirer was on her trail.

Baron said no campaign funds were tapped for the payments.
