For Congress


GAO is ready to work for Members of Congress. Whether you’re new to Congress or you just want a refresher, watch our video below to see what GAO can do for you.

How GAO Can Help Congress

A brief introduction to GAO specifically for our clients—the Members of Congress and their staffs.


Requests for GAO reports must come from congressional committees, subcommittees, or Members of Congress. In conjunction with Members of Congress, We developed our Congressional Protocols, which outline policies and procedures for accepting and completing work. Read more about how to request reports. 


Requests for GAO testimony should be made by a committee or subcommittee Chair in writing. GAO will strive to respond to all congressional requests for testimony. Read more about how to request a GAO witness on our Watchdog website that is exclusively for Members of Congress and staff.

Legal Decisions

GAO’s Office of the General Counsel regularly issues legal decisions regarding federal bid protests, appropriations law, and other legal matters. We provide various legal services to Congress, including:

  • Appropriations Law: GAO issues legal decisions to Congress and federal agencies on the use of, and accountability for, public funds, including ruling on potential violations of the Antideficiency Act.
  • Other Legal Work: GAO also issues other legal decisions. For example, we report on federal rules under the Congressional Review Act, and review the temporary filling of executive agency positions under the Federal Vacancies Reform Act. We also issue legal decisions in conjunction with this work.

Members of Congress can log into our Watchdog website for Congress to learn more about sending us request letters for an appropriations law decision or other legal work.
