Libby's Lawyers Hint at In-Depth Revelations

Lawyers for Vice President Dick Cheney's former top aide are signaling they may delve deeply at his criminal trial into infighting among the White House, the CIA and the State Department over pre-Iraq-war intelligence failures.

I. Lewis "Scooter" Libby's lawyers also are suggesting that the State Department -- not Libby -- may be to blame for leaking the identity of CIA officer Valerie Plame to the media.

Court papers filed late Friday raise the possibility a trial could become politically embarrassing for the Bush administration by focusing on the debate about whether the White House manipulated intelligence to justify the U.S.-led invasion of Iraq in March 2003.
