Former aide: Edwards surprised to learn about donations

Greensboro, North Carolina (CNN) - A friend and adviser to John Edwards testified Tuesday that the former presidential candidate appeared surprised to learn an elderly heiress sent money that ended up going to his mistress and another aide.

John Moylan, on the second day of defense testimony, said he believes Edwards learned about the checks from Rachel "Bunny" Mellon to campaign staffer Andrew Young for the first time in August 2008.
