The United States Secret Service (USSS or Secret Service) is a federal law enforcement agency under the Department of Homeland Security charged with conducting criminal investigations and protecting U.S. political leaders, their families, and visiting heads of state or government. Until 2003, the Secret Service was part of the Department of the Treasury, as the agency was founded in 1865 to combat the then-widespread counterfeiting of U.S. currency.
