Congress also maintains an investigative organization, the Government Accountability Office (GAO).
Founded in 1921 as the General Accounting Office, its original mission was to audit the budgets and financial statements sent to Congress by the Secretary of the Treasury and the Director of the Office of Management and Budget.
Today, the GAO audits and generates reports on every aspect of the government, ensuring that taxpayer dollars are spent with the effectiveness and efficiency that the American people deserve.
