# Congressional Oversight **Congressional oversight** is the power of Congress to review, monitor, and supervise the executive branch — the agencies it created, the programs it authorized, and the money it appropriated. The Constitution never names it. It is inferred from the powers that are named: legislating, appropriating, confirming, and impeaching. The Supreme Court has repeatedly held the investigative power to be an inherent auxiliary to the legislative power (*McGrain v. Daugherty*, 1927), bounded by a valid legislative purpose. ## The instruments - **Hearings** — the routine form, and the one most easily withheld: a chair who declines to schedule is exercising the oversight power in the negative. - **Subpoenas** — compulsory process for documents and testimony, issued under committee rules; enforceable in practice only through civil litigation, criminal contempt referral to DOJ, or the long-dormant inherent contempt power. - **The purse** — riders, reporting requirements, and fencing of funds attached to appropriations, which bind more reliably than any letter. - **Confirmation** — leverage applied to a nominee to extract commitments from an agency. - **The support agencies** — [[Government Accountability Office]] audits, [[Congressional Budget Office]] scoring, and [[Congressional Research Service]] analysis, plus the statutory [[Inspector General]] system inside each agency. ## Why it fails Oversight is structurally partisan: committees are controlled by the majority, and a majority that shares a president's party rarely investigates him. Jurisdiction is also allocated by committee, so a function moved between agencies can slip between committee lanes without any change to the rules — see [[Committee Oversight Crosswalk]]. Lapsed authorizations, blanket assertions of executive privilege, and the slow pace of subpoena enforcement litigation do the rest. ## See also - [[Committee Oversight Crosswalk]] — which committee is supposed to be watching which agency - [[Committees Hub]] · [[Congress Hub]] - [[Inspector General]] · [[Government Accountability Office]]
