White House refusing to share "continuity of government after disaster" plans with the Congress

Okay, that's creepy as hell. The White House has come up with a plan for how the government will survive after a catastrophic attack - say, a nuke hits the Congress during the State of the Union - but the White House is refusing to share the attack plan with members of Congress. That means that Bush and Cheney could have come up with a plan to put Pinocchio, or Harriet Miers, in charge of the government and there's nothing we can do about it. It doesn't even matter if the plan is unconstitutional. There is NOTHING we can do about it because the White House is above the law. The real question is what will the Congress do about it. Hold more hearings?
