Ex-Edwards aide: Donors' cash went into NC house

A former John Edwards aide has said that the bulk of nearly $1 million in cash that prosecutors say bought the silence of Edwards' mistress went to help build the aide's dream house.

Andrew Young testified for a fourth day Thursday at Edwards' campaign finance trial in Greensboro, N.C.

Edwards attorney Abbe Lowell peppered Young with questions about money that flowed into personal accounts controlled by Young and his wife. Young acknowledged most of the money helped build the couple's $1.5 million house near Chapel Hill, N.C.

Young has said he took secret payments from wealthy donors at Edwards' direction to help conceal the presidential contender's affair with a pregnant mistress.

Edwards has pleaded not guilty to six criminal charges and faces up to 30 years in prison if convicted.
