United States Congress

The United States Congress is the bicameral legislative branch of the federal government of the United States, composed of the Senate and the House of Representatives. It makes federal laws, sets portions of the federal budget, and provides for oversight of the executive branch, while also playing a role in constitutional amendments and federal appointments.

Structure and membership

The Congress consists of two chambers: the United States Senate and the United States House of Representatives. Senators serve six-year terms and represent their states, while Representatives serve two-year terms and represent congressional districts within states. Each chamber has officers and committees that manage legislation, hearings, and administrative matters.

Although the chambers operate independently, they share a common legislative process and are housed together in the United States Capitol. The Senate is chaired constitutionally by the vice president of the United States, who serves as President of the Senate, while the House is led by the Speaker of the United States House of Representatives.

Legislative process

Federal legislation typically begins when a bill is introduced in either the House or the Senate. After introduction, bills are referred to committees such as those found within the committee system, where members consider testimony, draft language, and amendments. A bill then proceeds through procedural steps, including votes in the originating chamber and further consideration in the other chamber.

When both chambers pass substantially different versions of a bill, the differences are often resolved through a conference committee. The final text is presented to the president for action. The Congress can also override a presidential veto with the required supermajorities under the Constitution, a mechanism that shapes the balance of powers between the branches.

Powers and constitutional role

Congress is empowered to enact laws under Article One of the United States Constitution and to oversee federal administration through hearings, investigations, and budgetary influence. Congressional oversight can involve both standing committees and special inquiry bodies, and it frequently examines agency operations, program effectiveness, and compliance with statutes.

Beyond ordinary legislation, Congress plays a role in constitutional change and national governance. For example, proposed amendments are submitted through procedures outlined in the Constitution, while federal appointments often require advice and consent through processes involving the U.S. Senate. Congress also controls key elements of public finance through its authority over taxation and spending legislation, including measures associated with the federal budget.

Sessions, elections, and continuity

Congress operates in multi-year terms, with each Congress spanning two years corresponding to successive election cycles for the House and staggered terms for the Senate. The federal government’s formal calendar includes congressional session, commonly divided into sessions within a given Congress.

Elections determine the composition of the House and the Senate, influencing committee leadership and legislative priorities. Continuity of governance is supported by longstanding House and Senate rules, the committee structure, and the practice of maintaining institutional knowledge across changing memberships and political coalitions.

Relationship with other branches

Congress interacts with the executive branch in several ways, including through the legislative authorization of programs and the oversight of executive agencies. Oversight often relies on statutory reporting requirements and hearings, and it may lead to changes in law. Congress also shapes executive practice via appropriations and constraints in annual spending measures.

In foreign policy and national security, the Congress’s role includes legislation and oversight that can complement executive actions. It also participates in war powers in a manner defined by statutes, appropriations, and constitutional interpretation, an area discussed in public policy debates involving the War Powers Resolution.
