Secret Service Fast Facts

(CNN)Here is some background information about the Secret Service, a federal agency tasked with protecting the president of the United States, among many other responsibilities.

Facts

    In addition to protecting the First Family, the Secret Service also provides security for the vice president, the president-elect, the vice president-elect, former presidents and their families, presidential candidates, visiting heads of state and representatives of the United States performing special missions overseas.
    After September 11, 2001, the Secret Service took on new responsibilities, overseeing security at non-political events that could be targets for terrorists, like the Super Bowl. Even as the scope of its mission broadened, the agency did not receive adequate funding, according to a House Oversight Committee report. Budget cuts, poor management and low morale led to an exodus of employees. Between 2011 and 2015, the number of full-time workers at the agency fell from 7,024 to 6,315, according to the House Oversight Committee.
