Her husband lied
A member of the media went to the administration and mentioned that his wife was a CIA agent
A different member of the media noted a comment claiming that she was a CIA agent
A special prosecutor was called for to investigate the latter
The witch hunt yielded nothing
but perhaps...perhaps, a case can be made that someone who forgot a conversation of two years ago intentionally failed to remember it.

Got it?

With the CIA constantly being on the wrong side of the facts Valerie began to worry that hher job was in jeopardy. So she found a rich diplomat (Joe Wilson) to support her. Joe then made her cover useless by marrying her so she got a paper pushing job at Langley. In retaliation for cutbacks at the CIA They sent Wilson on a foreign mnission which he screwed up as planned. Then they planted a company phone directory in Novak's office. When Novak found that valerie had been an agent they sprung the trap blaming it on Rove. The rest is history (cia-style).

Or alternatively,

Valerie Plame was or was not a covert spy as she went daily to her desk job at the CIA (maybe not the most effective way to remain covert);

She suggested her husband go to Niger to scope out whether Iraq was seeking yellow cake uranium advance their weapons of mass destruction.

Joe Wilson had a nice junket at the taxpayers' expense.

Joe Wilson wanted to promote his book.

He accused the Bush administration of lying about WMD - apparently some timeline discrepancy between his claim and the date of the report.

He and his wife had a nice photo taken for Vanity Fair cover shot in a convertible.
