History: Regarded as intensely secretive and protective of his boss, Libby was the vice president's most powerful aide and one of the handful of architects of the Bush administration's war-time policy and strategy. In the summer of 2003, he discussed with three journalists a trip to Niger by former ambassador Joseph C. Wilson IV, who was sent to investigate evidence that Iraq was seeking material for nuclear weapons and found the evidence lacking. Libby denies disclosing that Wilson's wife, Valerie Plame, was an undercover CIA operative. Today's indictments essentially charge Libby with lying to FBI agents and a grand jury about those conversations to protect Cheney.
