Cheney and Libby lied to the Senate

Murray Waas:

"Vice President Cheney and his chief of staff, I. Lewis "Scooter" Libby, overruling advice from some White House political staffers and lawyers, decided to withhold crucial documents from the Senate Intelligence Committee in 2004 when the panel was investigating the use of pre-war intelligence that erroneously concluded Saddam Hussein had weapons of mass destruction, according to Bush administration and congressional sources.

Had the withheld information been turned over, according to administration and congressional sources, it likely would have shifted a portion of the blame away from the intelligence agencies to the Bush administration as to who was responsible for the erroneous information being presented to the American public, Congress, and the international community."
