Established by Article I of the Constitution, the Legislative Branch consists of the House of Representatives and the Senate, which together form the United States Congress. The Constitution grants Congress the sole authority to enact legislation and declare war, the right to confirm or reject many Presidential appointments, and substantial investigative powers.
The House of Representatives is made up of 435 elected members, divided among the 50 states in proportion to their total population. In addition, there are 6 non-voting members, representing the District of Columbia, the Commonwealth of Puerto Rico, and four other territories of the United States. The presiding officer of the chamber is the Speaker of the House, elected by the Representatives. He or she is third in the line of succession to the Presidency.
Members of the House are elected every two years and must be 25 years of age, a U.S. citizen for at least seven years, and a resident of the state (but not necessarily the district) they represent.
The House has several powers assigned exclusively to it, including the power to initiate revenue bills, impeach federal officials, and elect the President in the case of an electoral college tie.
The Senate is composed of 100 Senators, 2 for each state. Until the ratification of the 17th Amendment in 1913, Senators were chosen by state legislatures, not by popular vote. Since then, they have been elected to six-year terms by the people of each state. Senator’s terms are staggered so that about one-third of the Senate is up for reelection every two years. Senators must be 30 years of age, U.S. citizens for at least nine years, and residents of the state they represent.
The Vice President of the United States serves as President of the Senate and may cast the decisive vote in the event of a tie in the Senate.
The Senate has the sole power to confirm those of the President’s appointments that require consent, and to ratify treaties. There are, however, two exceptions to this rule: the House must also approve appointments to the Vice Presidency and any treaty that involves foreign trade. The Senate also tries impeachment cases for federal officials referred to it by the House.
In order to pass legislation and send it to the President for his signature, both the House and the Senate must pass the same bill by majority vote. If the President vetoes a bill, they may override his veto by passing the bill again in each chamber with at least two-thirds of each body voting in favor.
The Legislative Process
The first step in the legislative process is the introduction of a bill to Congress. Anyone can write it, but only members of Congress can introduce legislation. Some important bills are traditionally introduced at the request of the President, such as the annual federal budget. During the legislative process, however, the initial bill can undergo drastic changes.
After being introduced, a bill is referred to the appropriate committee for review. There are 17 Senate committees, with 70 subcommittees, and 23 House committees, with 104 subcommittees. The committees are not set in stone, but change in number and form with each new Congress as required for the efficient consideration of legislation. Each committee oversees a specific policy area, and the subcommittees take on more specialized policy areas. For example, the House Committee on Ways and Means includes subcommittees on Social Security and Trade.
A bill is first considered in a subcommittee, where it may be accepted, amended, or rejected entirely. If the members of the subcommittee agree to move a bill forward, it is reported to the full committee, where the process is repeated again. Throughout this stage of the process, the committees and subcommittees call hearings to investigate the merits and flaws of the bill. They invite experts, advocates, and opponents to appear before the committee and provide testimony, and can compel people to appear using subpoena power if necessary.
If the full committee votes to approve the bill, it is reported to the floor of the House or Senate, and the majority party leadership decides when to place the bill on the calendar for consideration. If a bill is particularly pressing, it may be considered right away. Others may wait for months or never be scheduled at all.
When the bill comes up for consideration, the House has a very structured debate process. Each member who wishes to speak only has a few minutes, and the number and kind of amendments are usually limited. In the Senate, debate on most bills is unlimited — Senators may speak to issues other than the bill under consideration during their speeches, and any amendment can be introduced. Senators can use this to filibuster bills under consideration, a procedure by which a Senator delays a vote on a bill — and by extension its passage — by refusing to stand down.
