The main function of the legislative branch is to make laws. The legislative branch is composed of two houses, the Senate and the House of Representatives, and its primary job is to research, write, and pass legislation. The legislative branch also represents constituents and performs oversight functions for the executive branch.The bicameral legislature was established as a compromise during the Constitutional Convention, leading to the formation of the Senate, where each state has equal representation, and the House of Representatives, with representation based on each state's population. According to Article I of the U.S. Constitution, only Congress has the authority to enact legislation, affirming the legislative branch as the primary lawmaking body of the national government.
