What Committees Do

Congress has too many issues to handle as a single body of 535 people. So it divides the work among committees — small groups of members who specialize in specific policy areas like agriculture, defense, taxes, or healthcare.

When a bill is introduced, the Speaker of the House or Senate leadership refers it to the committee with jurisdiction over that topic. A bill about farm subsidies goes to the Agriculture Committee. A bill about military spending goes to Armed Services. A bill about taxes goes to Ways and Means (House) or Finance (Senate).

The committee chair — always from the majority party — has enormous power. They decide which bills get hearings, which get votes, and which sit on the shelf forever. This is why committee chairs are some of the most powerful people in Washington, even though most Americans can't name them.

Committees hold hearings where they invite experts, affected citizens, and government officials to testify. Then they may "mark up" the bill — literally going through it line by line, debating changes, and voting on amendments. If the committee votes to "report" the bill favorably, it goes to the full chamber for a vote. If they don't, the bill effectively dies in committee — which is the fate of most legislation.

Each committee also has subcommittees that focus on narrower topics. The Armed Services Committee, for example, has subcommittees for personnel, readiness, and strategic forces. Subcommittees do the initial work, then pass bills up to the full committee.

There are also "select" or "special" committees that handle investigations and oversight rather than legislation, like the Intelligence Committees that oversee the CIA and NSA.

Why this matters: if you want to know why a bill isn't moving, look at which committee has it and who chairs that committee. The committee system is the single biggest bottleneck — and the single biggest gatekeeper — in the legislative process.
