paragraph_text: Signing and vetoing bills
  
  The president's most significant legislative power derives from the Presentment Clause, which gives the president the power to veto any bill passed by Congress. While Congress can override a presidential veto, it requires a two-thirds vote of both houses, which is usually very difficult to achieve except for widely supported bipartisan legislation. The framers of the Constitution feared that Congress would seek to increase its power and enable a "tyranny of the majority", so giving the indirectly elected president a veto was viewed as an important check on the legislative power. While George Washington believed the veto should only be used in cases where a bill was unconstitutional, it is now routinely used in cases where presidents have policy disagreements with a bill. The veto – or threat of a veto – has thus evolved to make the modern presidency a central part of the American legislative process.
  
  Specifically, under the Presentment Clause, once a bill has been presented by Congress, the president has three options:
  
  In 1996, Congress attempted to enhance the president's veto power with the Line Item Veto Act. The legislation empowered the president to sign any spending bill into law while simultaneously striking certain spending items within the bill, particularly any new spending, any amount of discretionary spending, or any new limited tax benefit. Congress could then repass that particular item. If the president then vetoed the new legislation, Congress could override the veto by its ordinary means, a two-thirds vote in both houses. In Clinton v. City of New York, 524 U.S. 417 (1998), the U.S. Supreme Court ruled such a legislative alteration of the veto power to be unconstitutional.
