"The C.I.A. suspected that Aldrich Ames had given Mrs. Wilson's name (along with those of other spies) to the Russians before his espionage arrest in 1994," revealed the New York Times on Saturday.
In a column revealing the critical information for the first time since the Leakgate scandal exploded two weeks ago, Times columnist Nicholas Kristof explained that the Ames tip compromised Valerie Plame's undercover secrecy so thoroughly that "she was brought back to Washington for safety reasons."
At the time, he noted, Mrs. Wilson "was already in transition away from undercover work to management, and to liaison roles with other intelligence agencies. So this year, even before she was outed, she was moving away from 'noc' which means non-official cover."
