Which federal agency oversees the Federal Protective Service?

The Federal Protective Service operates under the Department of Homeland Security (DHS). This oversight provides the FPS with the necessary resources and support to fulfill its mission of protecting federal facilities, dignitaries, and other key assets. The Department of Homeland Security was established to improve the United States' ability to respond to and prevent various threats and emergencies, making it a suitable home for the Federal Protective Service, which plays a pivotal role in maintaining security and safety for federal entities.

In this context, the other agencies listed do not have jurisdiction over the Federal Protective Service. The Department of Justice typically focuses on issues related to law enforcement and federal legal matters, while the Federal Bureau of Investigation is primarily concerned with counter-terrorism, criminal investigations, and intelligence. The Department of Defense primarily deals with military operations and national security as it pertains to armed forces, leaving the responsibilities for federal protection and facility security to the Department of Homeland Security.
