See U.S. Department of Justice FOIA Information page

Like all federal agencies, the Department of Justice (DOJ) generally is required under the Freedom of Information Act (FOIA) to disclose records requested in writing by any person. However, agencies may withhold information pursuant to nine exemptions and three exclusions contained in the statute. The FOIA applies only to federal agencies and does not create a right of access to records held by Congress, the courts, or by state or local government agencies. Each state has its own public access laws that should be consulted for access to state and local records. Each federal agency is responsible for meeting its FOIA responsibilities for its own records. A list of Principal FOIA Contacts At Federal Agencies is available from the Department of Justice site. Likewise, each Department of Justice component is responsible for processing FOIA requests for the records that it maintains.
