In October of 2003, Pincus cowrote a story for The Washington Post which described a July 12, 2003 conversation between an unnamed administration official and an unnamed Post reporter. The official told the reporter that Iraq war critic Joe Wilson’s wife Valerie Plame worked for the CIA’s nonproliferation division, and suggested that Plame had recommended her husband to investigate reports that Iraq’s government had tried to buy uranium in Niger. It later became clear that Pincus himself was the Post reporter in question. Special Counsel Patrick Fitzgerald issued a grand jury subpoena to Pincus on August 9, 2004, in an attempt to discover the identity of Pincus’ secret informant. On August 20, the Post filed a motion to quash the subpoena, but after Pincus’ source came forward to speak with investigators, Pincus gave a deposition to Fitzgerald on September 15; Pincus recounted the 2003 conversation to Fitzgerald but still did not name the administration official. In a public statement afterward, Pincus said that the special prosecutor had dropped his demand that Pincus reveal his source. On February 12, 2007, Pincus admitted to Scooter Libby’s lawyer, William Jeffress Jr, that it was former White House Press Secretary Ari Fleischer that told him of the identity of Valerie Plame and her job with the CIA. Pincus was interviewed about his involvement in the Plame affair, and his refusal to identify his source, in the first episode of Frontline’s documentary “News War”.
