Breaking her public silence today, Valerie Plame testified before a House Oversight Committee. The wife of former Ambassador Joseph Wilson, who criticized the Bush Administration’s rationale for the war in Iraq, called herself the only covert CIA operative whose identity was disclosed by her "very own government," and said she felt "hit in the gut" on being outted by syndicated columnist Robert Novak. During the trial of Lewis "Scooter" Libby, there was testimony that he and Vice President Cheney had a role in public disclosures of her status.
