That fear, he said, peaked during a car ride "out in the middle of nowhere" with Edwards. During that ride, "all I could think about was Vince Foster," Young said, referring to the former aide to President Clinton who committed suicide in a Washington, D.C., park. Foster's death has been the subject of conspiracy theorists who speculated that he was killed to cover up a White House scandal.
"Did I think Edwards was capable? No," Young said. "But I was scared, genuinely scared, for me and my family."
Edwards' lawyers also lashed out at Young, his former confidant, before the book was released Saturday. Lawyers for Edwards, who had previously declined to comment on the allegations made in "The Politician," issued a statement Friday questioning Young's motives.
"While we have not had an opportunity to view the interview or read the book, we urge extreme caution by everyone involved. From media reports, it is obvious that there are many allegations which are simply false. It appears that Andrew Young is primarily motivated by financial gain and media attention," the statement said.
Young said he has saved voice mail messages and e-mails from Edwards and his camp proving that he had been asked to help the one-time presidential nominee hide Hunter while he made a bid for the White House, his cancer-stricken wife by his side.
He got the call asking to cover up Edwards' paternity of Hunter's baby while shopping for a turtle aquarium for his children, he told "GMA" on Monday. He said he agreed, not only out of loyalty for Edwards and compassion for Edwards' terminally ill wife, but because he had been assured by "two very powerful people" that every viable Democratic presidential hopeful had something to hide.
"We were convinced by the people that were talking to us about this that all of the candidates had skeletons in the closet," he said, adding that he doesn't believe that accusation now. "I'm not making a charge that it's true."
