Valerie Plame

No matter how the White House tries to spin it...whether Armitage ALSO leaked Plame's name, the facts remain that the White House wanted to smear Joe Wilson and used his wife's CIA position to try to shut him up. They failed and instead attained their other goal, to muddy the intelligence waters on WMDs for years to come.
What Valerie Plame Really Did at the CIA-David Corn (The Nation, Sept. 5, 2006)
Valerie Wilson was no analyst or paper-pusher. She was an operations officer working on a top priority of the Bush Administration. Armitage, Rove and Libby had revealed information about a CIA officer who had searched for proof of the President's case. In doing so, they harmed her career and put at risk operations she had worked on and foreign agents and sources she had handled.

Valerie Plame was recruited into the CIA in 1985, straight out of Pennsylvania State University. After two years of training to be a covert case officer, she served a stint on the Greece desk, according to Fred Rustmann, a former CIA official who supervised her then. Next she was posted to Athens and posed as a State Department employee. Her job was to spot and recruit agents for the agency. In the early 1990s, she became what's known as a nonofficial cover officer. NOCs are the most clandestine of the CIA's frontline officers. They do not pretend to work for the US government; they do not have the protection of diplomatic immunity. They might claim to be a businessperson. She told people she was with an energy firm. Her main mission remained the same: to gather agents for the CIA.

She was eventually given a choice: North Korea or Iraq. She selected the latter. Come the spring of 2001, she was in the CPD's modest Iraq branch. But that summer--before 9/11--word came down from the brass: We're ramping up on Iraq. Her unit was expanded and renamed the Joint Task Force on Iraq. Within months of 9/11, the JTFI grew to fifty or so employees. Valerie Wilson was placed in charge of its operations group.

When the Novak column ran, Valerie Wilson was in the process of changing her clandestine status from NOC to official cover, as she prepared for a new job in personnel management. Her aim, she told colleagues, was to put in time as an administrator--to rise up a notch or two--and then return to secret operations. But with her cover blown, she could never be undercover again.
