The United States Secret Service begins operation.

The United States Secret Service is a federal law enforcement agency under the Department of Homeland Security tasked with conducting criminal investigations and providing protection to American political leaders, their families, and visiting heads of state or government. The Secret Service was, until 2003, part of the Department of the Treasury, due to their initial mandate of combating counterfeiting of U.S. currency. The agency has protected U.S. presidents and presidential candidates since 1901.
