The legislature, known as the Congress, consists of voting members divided between two chambers: Each state is represented by two Senators who serve six-year terms.
Representatives in the House are elected from single-member constituencies and serve two-year terms. Congress has sole powers to appropriate financial outlays, and operates through a committee system. Legislation must be approved by a majority in both chambers, then signed by the President, to become law.
The President can veto legislation, but a veto can be overridden by a two-thirds majority in each chamber.
