Security will be handled by the U.S. federal government with an agreement signed by the LA organizing committee and Department of Homeland Security (DHS) in February 2020, but it will not be involved in the Games' funding, covering only the aforementioned security costs.[45]
The Olympics are the second to take place in the United States since the September 11 attacks in 2001. Like the 2002 Winter Olympics in Salt Lake City, which took place five months after that attack, the United States Department of Homeland Security will designate the Olympics a National Special Security Event (NSSE). Due to this designation, the United States Secret Service will be in charge of security and will head a single chain of command.[44]
