John Edwards’ attorneys are moving to question the credibility of the prosecution’s star witness after the former aide spent three days on the stand detailing how Edwards went to great lengths to cover up his affair and love child. Andrew Young is expected to take the witness stand for a fourth day Thursday as the defense continues its cross-examination. As prosecutors look to prove Edwards tried to use nearly $1 million in campaign donations to hide his affair during his 2008 bid for the White House, defense lawyers are trying to point out inconsistencies in Young’s story — both in court testimony and previous statements like in his 2010 tell-all book, “The Politician.” So far, most of the alleged inconsistencies have concerned minor details and dates. But Edwards’ lead attorney Abbe Lowell was tough on Young on the witness stand Wednesday. In one case, he asked Young whether he had fallen in love with Edwards. “A lot of people in the country did,” Young replied. “Did you fall out of love with him?” Lowell asked. “I did, yes sir,” Young said. “You really hate him, don’t you?” Lowell asked. “I have mixed feelings,” Young said. Young recalled his last meeting of any substance with the former presidential candidate in August of 2008, during which Edwards denied any knowledge of the secret checks a wealthy heiress had been providing to pay for the luxury accommodations and travel of Edward’s lover, Rielle Hunter. Young said when he informed Edwards he had evidence of everything that had transpired, “He looked at me and he said, ‘You can’t hurt me, Andrew. You can’t hurt me.’” Edwards, who has pleaded not guilty to six counts of campaign finance violations, faces up to 30 years in prison and $1.5 million in fines if convicted.
