Learn what Young claims were Edwards' plans with Rielle Hunter after Elizabeth's death
Find out how Andrew Young and wife Cheri say they stumbled upon a "compromising tape"
Young's accounts paint a portrait of Elizabeth as a controlling wife beneath a collected exterior.
At the beginning of Edwards' relationship with Hunter, Young claims Elizabeth was aware of her husband's previous affairs and developed an elaborate system to keep tabs on him.
"She would call his room in the middle of the night to make sure he was there. She would put up acronyms for whoever would call in so that a casual woman or whatever couldn't get through and she would change them regularly. She would leave instructions at the hotel front desk for a woman not to be transferred other than her into his room," Young told ABC News.
Young said she would even monitor the cell phone records of Edwards' staff.
"That's how he started using my phone, or he would call my phone and I would do a three-way call into Rielle's phone so that Elizabeth couldn't see that he was talking to Rielle," Young said. "She would call me and say, 'Why were you and John talking for an hour?' And I would say, 'Basketball.'"
Edwards also had a "secret" cell phone, according to Young, which was called "the bat phone." Young said he typically answered the phone and took the phone at night for safe keeping, but in October 2006, when Edwards returned from a five-day trip to Uganda with Hunter, Elizabeth answered a call and heard a woman's voice on the line.
"[Edwards] went to bed and Elizabeth answered the phone and didn't say anything and Rielle just started saying lovey-dovey ... They [the Edwards] had a knock down brawl … He said that Elizabeth made him call the number back immediately and supposedly end the affair. And, of course, he used my phone to call [Hunter] to tell her it was ok," recalled Young.
At that point, Young told ABC News Elizabeth must not have known who was on the phone because for "several months after that, Rielle's name was on the daily schedule traveling with the senator."
By the time Edwards formally launched his 2008 campaign, the presidential hopeful was living two lives, Young said: a comfortable one with Elizabeth at their newly-constructed Chapel Hill mansion, and a private one with Hunter ducking in and out of hotel rooms on a multi-state announcement tour.
At a December 2006 rally at Southern Village in front of Edwards' Chapel Hill, N.C. headquarters, the Edwardses put a smile and waved to the crowds. There was no sign that just moments before, the candidate's two worlds had collided.
Following Edwards' request to keep Hunter away from Elizabeth, Young said he brought Hunter to a bathroom he didn't think Elizabeth would use, but instead the two women came face to face for the first time.
