This just in from a friend of mine:

As the September 11th Commission grills President Bush and Vice President Cheney about their contradictory statements today, we wanted to alert you to a powerful new tool to help journalists, activists and the public compare the Bush administration's claims against well-documented facts.

The Center for American Progress today launched a comprehensive

Claim vs. Fact database that documents statements from conservatives like President Bush, Vice President Cheney, Members of Congress and Fox News personalities, and compares those statements to the facts.

Each fact is sourced, and in many cases includes a web link directly to that source.
