Congress transferred USSS to the Department of Homeland Security (DHS) in 2002. Criminal investigation activities encompass financial crimes, identity theft, counterfeiting, computer fraud, and computer-based attacks on the nation’s financial, banking, and telecommunications infrastructure. Protection mission is the most prominent of the two, covering the President, Vice President, their families, former Presidents, and major candidates for those offices, along with the White House and the Vice President’s residence (through the Service’s Uniformed Division). Protective duties of the Service also extend to foreign missions in the District of Columbia and to designated individuals, such as the Homeland Security Secretary and visiting foreign dignitaries. Separate from these specific mandated assignments, USSS is responsible for certain security activities such as National Special Security Events (NSSEs), which include the major party quadrennial national conventions as well as international conferences and events held in the United States. -- See CRS Report RL34603, The U.S. Secret Service: An Examination and Analysis of Its Evolving Missions, 31 July 2008 U.S.A.
