9/11 Panel won't get extension
The White House has stonewalled them for months, making their job nearly impossible, but insists that they finish in May.

I'm having trouble finding a specific quote, but I recall that one of the few excuses the Bushies have left for invading Iraq is that Saddam was concealing evidence from weapons inspectors. Well, those same Bushies have been concealing evidence about 9/11 since, well, 9/11 (or earlier?). They already knew that they were going to invade Afghanistan and Iraq, so what difference did it make who actually did 9/11? (Especially if it made them, the Bushies, look bad, which it most assuredly would.)
