The House of Representatives

The House has 435 voting members. After each census, seats are divided among the states by population, and every state gets at least 1. A state with more than 1 seat elects each member from a separate , and in a state with just 1 seat, the member represents the whole state. All seats are on the ballot every 2 years. Washington, DC, Puerto Rico and 4 other territories also send members, but they cannot vote when the full House meets.

The Senate

Every state has 2 senators, no matter how many people live there, so the Senate has 100 members. Senators serve 6-year terms, and the terms are staggered, so about one-third of the seats are on the ballot every 2 years. The Seventeenth , ratified on April 8, 1913, gave voters the power to elect senators directly. Before that, state legislatures chose them.

Different jobs in each chamber

  • Bills to raise revenue must start in the House, though the Senate can amend them.
  • The House can impeach federal officials, and the Senate then holds the trial, where conviction takes two-thirds of the senators present.
  • Treaties need the approval of two-thirds of the senators present.
  • The Senate confirms or rejects the president’s nominees, such as federal judges.

For any bill to become law, both chambers must pass it in the same form.

State legislatures

Each state also has its own legislature, separate from Congress. In 49 states it has two chambers, a senate and a lower chamber. Many states call the lower chamber the house of representatives, but names vary, and New Jersey calls it the General Assembly. Nebraska has a single chamber of 49 senators. As of 2024, most states give lower-chamber members 2-year terms and state senators 4-year terms.

From the Constitution

All Bills for raising Revenue shall originate in the House of Representatives; but the Senate may propose or concur with Amendments as on other Bills.
