A division of the Department of Treasury, the Secret Service was established in 1865 to suppress counterfeit currency. Soon after, the Secret Service began investigating people who committed "frauds against the government." After the assassination of President McKinley in 1901, the Secret Service was assigned to full-time protection of the president. Former presidents elected before 1997 receive life-time protection from the Secret Service. The service still investigates counterfeiting and credit card fraud and maintains a most-wanted fugitives list. The service also maintains field offices in most states and some countries.
