The United States House of Representatives is one of the two houses of the United States Congress. It is frequently referred to as the House. The other house is the Senate.
The composition and powers of the House are established in Article One of the United States Constitution. The major power of the House is to pass federal legislation that affects the entire country although its bills must also be passed by the Senate and further agreed to by the U.S.
In addition to this basic power, the House has certain exclusive powers which include the power to initiate all bills related to revenue, the impeachment of federal officers, who are sent to trial before the Senate, and in cases wherein no candidate receives a majority of electors for President, the duty falls upon the House to elect one of the top three recipients of electors for that office, with one vote given to each state for that purpose.
The House is referred to as the lower house, with the Senate being the upper house, although the United States Constitution does not use that terminology. Both houses’ approval is necessary for the passage of legislation.
