Sen Arlen Specter (R-PA) is ready to take President Bush to court. He's preparing a bill that would let Congress sue the President over "signing statements."
Those are caveats the President has written upon signing more than 750 bills. In effect he says he's signing a bill -- but reserving the right to revise it, interpret it however he wants or simply ignore laws he doesn't like based on national security or constitutional grounds.
All Presidents have had signing statements on controversial bills. But President Bush has issued more of them than the Previous 42 Presidents combined. (USAToday)
