Legislative oversight

Legislative oversight is the examination of executive agencies and officials by a legislature, using tools such as hearings, investigations, and budgetary review.

Congressional hearing: A formal meeting in which a congressional committee gathers testimony, examines evidence, or considers legislation. Hearings let committees question officials and build a public record about agency conduct.
Separation of powers: A system that divides governmental authority among distinct branches to limit concentrated power. Oversight is one way the legislative branch checks executive authority.
Oversight of intelligence agencies: Legislative monitoring of intelligence organizations, their activities, budgets, and legal compliance. Intelligence oversight tests how scrutiny operates when secrecy limits public disclosure.
Judicial review: The power of courts to assess whether laws or government actions comply with a constitution or other governing law. Courts resolve legal questions, while legislatures also examine policy, administration, and spending.
Watergate scandal: A political scandal involving the 1972 break-in at Democratic National Committee headquarters and efforts to conceal it. The scandal prompted intensive congressional investigation of presidential misconduct.
Congressional subpoena: A compulsory demand issued by a congressional committee for testimony or documents. Subpoenas can compel evidence when voluntary cooperation fails.
Checks and balances: An arrangement in which branches of government can restrain one another's powers. Legislative oversight applies this broader principle to executive administration.
Government accountability: The obligation of public institutions and officials to explain and answer for their decisions and conduct. Oversight seeks explanations and consequences for executive actions.
Internal control: Policies and procedures within an organization designed to manage risk and ensure reliable operations. Internal controls operate inside agencies rather than through external legislative scrutiny.
Impeachment in the United States: The constitutional process by which the House charges federal officials and the Senate tries those charges. Oversight findings can inform impeachment, though investigation and impeachment are distinct powers.
