“On September 29, 2003, three days after it became known that the CIA had asked the Justice Department to investigate who leaked the name of covert CIA officer Valerie Plame, columnist Robert Novak telephoned White House senior adviser Karl Rove to assure Rove that he would protect him from being harmed by the investigation, according to people with firsthand knowledge of the federal grand jury testimony of both men,” Murray Waas reports in the National Journal.
