US House of Representatives

The United States House of Representatives is one of the two chambers of the United States Congress, with the other being the Senate. Its main function is to pass federal legislation, which must then be approved by the Senate before it can become law. The House also has the power to impeach government officials, including the President, and to initiate revenue-related bills. Congressional data is made available through the Congress.gov API, a REST API maintained by the Library of Congress that provides access to bills, members, committees, amendments, nominations, and treaties.
