national special security event

A National Special Security Event (NSSE) is declared by the United States Department of Homeland Security (DHS) to assume federal control of security measures normally employed by local law enforcement. It also releases federal funding for security plans. Though not declared by DHS (which did not yet exist), the first NSSE after the September 11, 2001 attacks was Super Bowl XXXVI. More recent NSSEs include the state funerals of Ronald Reagan and Gerald Ford, the 2004 Democratic National Convention, and the 2004 Republican National Convention.
