Christopher Dodd has introduced a bill that would undo the damage of the Military Commissions Act. In particular, it restores the right of habeas corpus to detainees. You can become a citizen cosponsor of the bill by clicking here.
There is also a charming video of Dodd explaining the act. He's at his desk, with his tie loosened, and a half full Styrofoam cup of coffee in front of him. I don't know if the look is deliberate, but it does project a "hard working legislator" image.
