As C&L says, people need to speak out about this:

Sen. Joe Lieberman, the only Democrat to endorse President Bush’s new plan for Iraq, has quietly backed away from his pre-election demands that the White House turn over potentially embarrassing documents relating to its handling of the Hurricane Katrina disaster in New Orleans. Senator Joe Lieberman has just taken the very surprising step of revealing to Newsweek that he will not use his chairmanship on the Homeland Security committee to aggressively probe the government's catastrophic failings in the wake of Hurricane Katrina.

There's no excuse for this other than to spit in the face of Democrats who Joe doesn't feel supported him in his moment of need, because after all that is what is most important in the situation. How does his good friend Mary Landrieu, who showed up in CT to campaign for him, feel?

Digby calls him "a vindictive old prick." I think that puts it mildly.
