Longtime Washington Post journalist and current assistant editor Bob Woodward testified Monday a senior administration official told him about CIA operative Valerie Plame nearly a month before her identity was thought to be first disclosed. The official appears to be someone other than Lewis Libby or Karl Rove. Woodward was questioned by Special Prosecutor Patrick Fitzgerald after the unnamed official alerted Fitzgerald of his conversation with Woodward. Citing a confidentiality agreement, Woodward and Post editors did not reveal the source’s identity. Post editors say Woodward only told them of the conversation last month.
