Libby May Have Tried to Mask Cheney Role

In the opening days of the CIA leak investigation in early October 2003, FBI agents working the case already had in their possession a wealth of valuable evidence. There were White House phone and visitor logs, which clearly documented the administration's contacts with reporters.

And they had something that law enforcement officials would later describe as their "guidebook" for the opening phase of the investigation: the daily, diary-like notes compiled by I. Lewis "Scooter" Libby, then Vice President Cheney's chief of staff, that chronicled crucial events inside the White House in the weeks before the identity of CIA operative Valerie Plame was publicly disclosed.

The investigators had much of this information before they sat down with Libby on Oct. 14, 2003, and first heard from him what prosecutors now allege was a demonstrably false version of what happened. Libby said that, when he told other reporters about the CIA operative and her marriage to Iraq war critic Joseph C. Wilson IV, he believed he had first learned the information from Tim Russert of NBC News and was merely passing along journalistic hearsay. This was an explanation made dubious by Libby's own notes, which showed that he previously had learned about Plame from his boss, Cheney.

In the aftermath of Libby's recent five-count indictment, this curious sequence raises a question of motives that hangs over the investigation: Why would an experienced lawyer and government official such as Libby leave himself so exposed to prosecutor Patrick J. Fitzgerald?
