Q. If I name cabinet agency ‘x’ as the only defendant in a FOIA lawsuit, do I serve the agency’s general counsel and the local U.S Attorney in addition to the agency at the 950 Pennsylvania address?

A. You’ll have to serve three entities: (1) the Attorney General (at 950 Pennsylvania Ave.); (2) the U.S. Attorney’s Office in the district where the suit is filed'; and (3) and the cabinet agency. See this handy guide from the Reporters Committee for Freedom of the Press:
