Ex- mistress of John Edwards testifies in campaign case

RALEIGH, N.C. (AP) - The former mistress of John Edwards spent much of the day in a federal courthouse in Raleigh where a grand jury was meeting Thursday, at a time when federal investigators are examining the two-time presidential candidate's finances.

Rielle Hunter walked into the building in the morning through a back entrance, holding a young child.

Edwards adamantly denied during a confessional interview with ABC News last summer that he had fathered a child with Hunter, and he welcomed a paternity test. His wife, Elizabeth, has said while promoting her book that she doesn't know if her husband is the father.

Former Edwards aide Andrew Young, who made a similar courthouse visit while the grand jury was sitting last month, said in 2007 he was the child's father.

Hunter said around the same that Young was the father and the birth certificate does not list a father's name.

Hunter's attorney, Michael Critchley, said outside the courthouse he did not expect his client to comment when she emerges.
