Paternity Questions Swirl as Elizabeth Edwards Speaks Out

John Edwards' ex-mistress reportedly is interested in seeking a paternity test for her 1-year-old daughter after Edwards' wife, Elizabeth, sparked fresh questions over whether the father might be her husband.

The former North Carolina senator and presidential candidate denied being the father of Frances Quinn Hunter during a TV interview in August. But Elizabeth Edwards, in an interview on "The Oprah Winfrey Show" that aired Thursday afternoon, didn't sound so sure.

"I've seen a picture of the baby," she said. "I have no idea. It doesn't look like my children, but I don't have any idea."

On Wednesday, one day after Oprah's production company released excerpts of the interview, The National Enquirer reported that Rielle Hunter, John Edwards' former mistress, is working with a lawyer to seek a paternity test from him.

That's a reversal from last August, when Hunter's attorney Robert Gordon released a statement saying she "will not participate in DNA testing or any other invasion of her or her daughter's privacy now or in the future."

Edwards said at the time that he would "welcome" a paternity test, and that because of the "timing" of his affair "it's not possible that this child could be mine." But he indicated that his apparent willingness to take the test would lead nowhere unless Hunter consented.

"I'm only one side. I can run only one side of the test, but I'm happy to participate in one," Edwards said at the time.

It's unclear whether Edwards would be as willing to submit to a test if Hunter is on board with the idea.

His wife said in the interview Thursday that, "I suppose it would be easy" to determine the paternity but she did not press for a test.

"Whatever the facts are doesn't change my life in a sense," she said, adding that if the child is her husband's, "then that would be a part of John's life, but it's not part of mine."

When it was initially reported that Edwards was the love child's father, a former aide to the ex-senator, Andrew Young, claimed paternity.

Gordon, reached by Thursday, said he did not know whether Hunter was seeking a paternity test and that he no longer represents her.

"I haven't been involved in that in a long time," Gordon said. "I can't speak to anything. I don't know anything."

Pigeon O'Brien, a former close friend of Hunter's who publicly questioned Edwards' account of the affair last year, said in an e-mail to that she didn't know whether Hunter is seeking a paternity test. But she added: "It all has to do with [Elizabeth Edwards'] book and the resulting chaos."

In her book, "Resilience," due out next week, Elizabeth Edwards calls Hunter's life "pathetic" and writes that she threw up when she learned of her husband's affair.

A source reportedly told the Enquirer that Hunter decided to abandon the "cover-up" over the paternity of her daughter after learning about the contents of Elizabeth Edwards' book, in which she reportedly refers to the baby only as "it" and does not name Hunter.

While Andrew Young, a former Edwards campaign aide, claimed to be the father of Frances Hunter, another former campaign worker told last summer that he and Hunter had "no relationship." The birth certificate for Frances Quinn Hunter does not list a father.

The question of paternity isn't the only matter still dogging Edwards in the wake of the affair and his subsequent confession. Federal investigators are also looking into how he's managed his campaign funds -- finance questions arose last year after his political action committee  paid more than $100,000 to Hunter's company for the production of short videos.
