Ex-adviser: Edwards cursed him after being warned to stay away from mistress From Ted Metzger, CNN May 4, 2012 -- Updated 2202 GMT (0602 HKT) Peter Scher testifies in the trial of John Edwards, whom he advised in his presidential run Scher says he had two talks with Edwards about his relationship with Rielle Hunter He says Edwards first denied affair, then told Scher to "back off" after being pressed again Edwards is accused of raising and not reporting money that was used to cover up his affair Greensboro, North Carolina (CNN) -- A former adviser recalled Friday how he urged John Edwards to steer clear of a campaign videographer, later revealed to be his mistress. But the then-presidential candidate refused, Peter Scher said in court. He said that "I should back off, he didn't need a baby sitter," Scher testified during Edwards' felony trial. The former outside adviser's testimony Friday provided jurors with yet another perspective on Edwards' handling of questions about his relationship with Rielle Hunter, whom he later admitted to having an affair and fathering a child with while seeking the Democratic Party's 2008 presidential nomination. That money was used to pay for Hunter's living and medical expenses, travel and accommodations to keep the mistress out of sight while Edwards made his second White House run, prosecutors say. While on the stand in federal court in Greensboro, North Carolina, Scher said that campaign staffer Josh Brumberger had asked for his help, given "gossip" about questionable behavior involving Edwards and Hunter. After that request, Scher said he met with the former U.S. senator from North Carolina in New York in September 2007 to address "the concerns" in person. In that conversation, Edwards said: "So you're asking if I'm sleeping with her?" recalled Scher, a lawyer who now works at JPMorgan Chase. The then-adviser said he replied, "That's precisely what I'm asking." Denying the affair, Edwards did "agree" that Hunter should no longer travel with his campaign. Scher said he had warned the then-married Edwards that he shouldn't continue his presidential run if he was, indeed, having an affair -- adding, "The truth (will) come out." Hunter briefly left the campaign trail but, weeks later, was back on the road with the Democrats' 2004 vice presidential nominee, Scher said. That led to what the former adviser described as his "pretty heated" phone conversation with Edwards that October. Scher said he ended his relationship with Edwards after the candidate cursed him. If convicted on all six felony counts he's charged with -- including conspiracy and making false statements -- Edwards could face up to 30 years in prison. CNN's Joe Johns contributed to this report.
