How the legislative branch checks whether laws are actually being carried out as intended.
Oversight turns government from a promise into a record. Committees question officials, request documents, hold hearings, review spending, and examine agency performance — the ongoing, ordinary mechanism by which Congress checks the executive branch, not just a tool for dramatic scandals.
Oversight is Congress checking whether public money, programs, agencies, contractors, and officials are doing what the law requires.

Where to Actually Find Oversight Records
Start with the committee, not the agency
Start with the relevant House or Senate committee’s website — not the agency being overseen. From there, look for hearing pages, written testimony, committee reports, video, transcripts, and related bills or appropriations language. Comparing an agency’s own public testimony against its budget, rulemaking, and inspector general records is usually where the real gaps show up.
Oversight is strongest when it’s tied to an actual legislative purpose
A common misconception is that Congress can investigate anything it wants, for any reason, using its oversight powers. Courts have generally required that oversight serve a legitimate legislative purpose — informing future legislation, checking how money was spent, or evaluating whether a law is working as intended — rather than functioning as an open-ended power to investigate for its own sake. This distinction has real legal consequences in disputes over subpoena enforcement.
