United States Congress is the bicameral federal legislature established by the Constitution in 1789 that enacts national law, controls federal appropriations, and oversees the Executive Branch. It consists of a Senate and a House of Representatives whose powers, composition, and procedures are defined by the Constitution and subsequent statutes such as the Twelfth Amendment and the Seventeenth Amendment. Its actions have shaped major national events from the Louisiana Purchase debates through the New Deal era to the Civil Rights Act of 1964 and modern budgetary disputes.

History

The framers at the Philadelphia Convention designed a bicameral legislature informed by debates between proponents of the Virginia Plan and the New Jersey Plan, culminating in the Connecticut Compromise. Early congressional practice was influenced by figures such as James Madison, Alexander Hamilton, and George Washington, and by conflicts including the War of 1812 and the Nullification Crisis. The antebellum period saw contentious legislative battles over the Missouri Compromise and the Compromise of 1850, while reconstruction after the American Civil War involved pivotal statutes like the Fourteenth Amendment and the Reconstruction Acts. Twentieth-century transformations—driven by leaders such as Theodore Roosevelt, Woodrow Wilson, and Franklin D. Roosevelt—expanded federal roles through measures like the Federal Reserve Act, the New Deal, and wartime legislation during World War II. Later moments, including the Watergate scandal, the passage of the Affordable Care Act, and responses to the September 11 attacks illustrate evolving oversight, investigatory authority, and national security legislation.

Structure and Powers

Constitutional designates the House as the chamber tied to population and the Senate as the chamber representing states. Enumerated powers include taxation, coining money, regulating interstate commerce, declaring war, and raising and supporting armed forces, while checks include the Senate’s advice and consent on appointments and treaties and the House’s power of impeachment with the Senate conducting trials. Landmark judicial interpretations in cases like Marbury v. Madison and McCulloch v. Maryland affected congressional authority, and statutes such as the War Powers Resolution sought to define interbranch limits. Budgetary mechanisms, including the Congressional Budget Act of 1974 and annual appropriations, shape federal spending and fiscal policy.

Legislative Process

A bill may be introduced in either chamber (subject to revenue origins in the House) and is referred to committee, debated, amended, and must pass both chambers before presentment to the President. Reconciliation procedures, used to pass budget-related statutes such as the Tax Cuts and Jobs Act of 2017, provide expedited consideration in the Senate. Filibuster rules in the Senate and the House Rules Committee’s control of floor amendments critically affect outcomes; rules have changed through precedents and cloture motions. Conference committees reconcile differences, and presidential vetoes can be overridden by two-thirds votes, a mechanism used during episodes like the Clinton administration vetoes and later overrides.

Leadership and Organization

Each chamber’s internal leadership—such as the Speaker in the House and the Majority Leader and Minority Leader in the Senate—organizes floor activity, party strategy, and committee assignments; prominent leaders have included Henry Clay, Sam Rayburn, Lyndon B. Johnson, and Mitch McConnell. Party caucuses and conferences, including the House Democratic Caucus and the Senate Republican Conference, set policy priorities and vote tallies. Institutional officers such as the Clerk, the Secretary of the Senate, and the Architect of the Capitol support operations, while the Library of Congress and the Congressional Research Service provide research and archival services.

Membership and Elections

House members serve two-year terms and represent congressional districts apportioned after the decennial census under the reapportionment process; Senators serve six-year staggered terms representing states. Elections involve primary systems, general elections, and rules shaped by cases like Baker v. Carr and Reynolds v. Sims that addressed representation and malapportionment. Campaign finance is governed by statutes and decisions such as the Federal Election Campaign Act and Citizens United v. Federal Election Commission, while redistricting controversies engage actors like state legislatures, independent commissions, and the Supreme Court.

Committees and Congressional Offices

Standing committees—examples include Ways and Means, Judiciary, Appropriations, and Finance—draft legislation, hold hearings, and exercise oversight; select and joint committees address specific issues such as the House Select Committee on the January 6 Attack. Congressional offices like the Congressional Budget Office, the Government Accountability Office, and the Office of Congressional Budget (note: CBO) provide analysis, audit federal programs, and support legislative decision-making. Committee chairs and ranking members, historically powerful figures such as Sam Rayburn and Robert Byrd, influence agendas through control of markups and hearings.

Relationship with Other Branches and Federalism

Interactions with the President include advice and consent, oversight, and statutory checks such as impeachment; notable confrontations occurred during the Watergate scandal and the Iran–Contra affair. Judicial review by the Supreme Court shapes congressional reach via rulings like United States v. Lopez and Shelby County v. Holder. Relations with states are mediated through federalism mechanisms including conditional grants, preemption under statutes like the Commerce Clause interpretations, and litigation between states and Congress that has reached the high court in cases such as Arizona v. United States and NFIB v. Sebelius.
