Moderate Senators on both sides of the aisle are quietly considering a range of options that would attempt at the very least to delineate the President's authority, if not roll it back. Bush's claims of wartime license are so great-the White House and Justice Department have argued that the Commander in Chief's pursuit of national security cannot be constrained by any laws passed by Congress, even when he is acting against U.S. citizens. Some Senators are considering a constitutional amendment to limit Bush's recenly claimed, extraordinary powers that place the executive office above the other branches of government, and greatly threaten the balance of powers established by the Constitution.
