Former aide faces more questions at John Edwards trial

Greensboro, North Carolina (CNN) – A former campaign aide of John Edwards will face more questions Thursday, a day after he was quizzed about his motives and asked whether he made up stories about how Edwards allegedly concealed contributions from campaign donors.

Andrew Young, the former aide, testified Wednesday on day three of the trial at U.S. District Court in Greensboro, North Carolina. He is considered the government's star witness against Edwards, who is accused of using hundreds of thousands of dollars of donations to conceal his affair with a campaign videographer without reporting the money to federal authorities.
