what agency oversees the secret service

The United States Secret Service is overseen by the U.S. Department of Homeland Security (DHS).

Who’s in charge, in plain terms

• The Secret Service is a federal law‑enforcement agency that sits inside the Department of Homeland Security, not the Department of Justice or the Pentagon.

• By law, the Director of the Secret Service reports directly to the Secretary of Homeland Security and not through any other DHS official.

• Until 2003, the Secret Service was part of the Department of the Treasury , but control shifted to DHS when that department was created after 9/11.

So if you’re asking “what agency oversees the Secret Service,” the answer is: it operates as its own distinct agency, but it is overseen at the Cabinet level by the Department of Homeland Security.

TL;DR: The Secret Service is a standalone federal agency that is organizationally under the U.S. Department of Homeland Security, whose Secretary is the top official overseeing it.
