An unclassified summary of outed CIA officer Valerie Plame's employment history at the spy agency, disclosed for the first time today in a court filing by Special Counsel Patrick Fitzgerald, indicates that Plame was "covert" when her name became public in July 2003.

The summary is part of an attachment to Fitzgerald's memorandum to the court supporting his recommendation that I. Lewis "Scooter" Libby, Vice President Cheney's former top aide, spend 2-1/2 to 3 years in prison for obstructing the CIA leak investigation.

The nature of Plame's CIA employment never came up in Libby's perjury and obstruction of justice trial.

The unclassified summary of Plame's employment with the CIA at the time that syndicated columnist Robert Novak published her name on July 14, 2003 says, "Ms. Wilson was a covert CIA employee for who the CIA was taking affirmative measures to conceal her intelligence relationship to the United States."

Plame worked as an operations officer in the Directorate of Operations and was assigned to the Counterproliferation Division (CPD) in January 2002 at CIA headquarters in Langley, Virginia.

The employment history indicates that while she was assigned to CPD, Plame, "engaged in temporary duty travel overseas on official business." The report says, "she traveled at least seven times to more than ten times." When overseas Plame traveled undercover, "sometimes in true name and sometimes in alias -- but always using cover -- whether official or non-official (NOC) -- with no ostensible relationship to the CIA."
