"Rielle is a very unique personality," Davis said. "Everyone else on the team had a political background. Rielle didn't have that sort of resume. . . . She talked a lot about meditation and yogis."
Davis, who traveled with Edwards in 2006 and 2007, is one of several former aides who have testified about their suspicion or knowledge of the affair during Edwards' campaign finance corruption trial. At issue is money from wealthy donors that was used in an attempt to keep the candidate's affair with Hunter out of public view.
Edwards' attorneys have said he didn't know about the money, and he's pleaded not guilty to six counts related to campaign-finance violations. He faces up to 30 years in prison and $1.5 million in fines if convicted on all counts.
Hunter's contract with the Edwards organization wasn't renewed at the end of 2006, days after a campaign event at which Davis said he saw Edwards' wife crying after seeing her husband with the videographer.
But Davis said Hunter didn't go away. In February 2007, he ran into her in an elevator at the candidate's Detroit hotel.
"We exchanged brief pleasantries," said Davis. "I would have preferred not to have seen her."
When he saw that she pushed the button for Edwards' floor - where Davis also had his room - he stopped on another floor just so he could get into a different elevator car. Shortly after, he was on the phone with his wife to express his shock at seeing Hunter. He heard a knock at the door of his room. It was the mistress, who came in to talk.
"She told me that she and Sen. Edwards were very much in love and that he was concerned that I had seen her," Davis said.
The next morning, Edwards called Davis to his room and, without being asked, denied that he was having an affair with Hunter.
"He told me she was crazy and that we should make sure she didn't talk to him," Davis said.
Asked if he believed Edwards, Davis replied: "I chose to believe him."
But not long after his encounter with Hunter, a change was made in hotel arrangements. Davis said he'd always stayed in a room close to the candidate, but that the staff began staying on a different floor than Edwards.
