The Government Accountability Office (formerly the General Accounting Office) is part of the legislative branch of government. It is known as "the investigative arm of Congress" and "the congressional watchdog." GAO supports the Congress in meeting its constitutional responsibilities and helps improve the performance and accountability of the federal government for the benefit of the American people.
