After the September 11th attacks, the House and Senate intelligence committees set about the task of finding what, if anything, went wrong with U.S. intelligence efforts. But the committees struggled under the sheer size of the burden; both their members and other members of Congress began to get frustrated at the pace of the investigation. Progressives and Democrats in general began to wonder whether the Bush administration wanted the investigation to go slowly, to postpone uncovering embarrassing lapses in intelligence. They proposed an amendment to the bill authorizing intelligence programs for 2003 that would create an independent, bipartisan commission to investigate lapses in the intelligence community. Progressives voted "yes" on this amendment, which won support from all but four Democrats and a sizeable minority of Republicans. The amendment passed 219-188.
