EPIC has filed a Freedom of Information Act lawsuit for records about "Hemisphere," a massive telephone record collection program operated by the Drug Enforcement Agency in cooperation with AT&T. Under the program, law enforcement agencies access billions of detailed customer phone records, including location data, dating back to 1987 in routine criminal matters unrelated to national security. EPIC filed the complaint after the federal agency failed to respond to EPIC's FOIA request for information about the operation and legal authority for the program. EPIC has previously challenged the NSA's bulk collection of telephone records in a petition to the US Supreme Court. For more information, see EPIC: In re EPIC (NSA Telephone Record Surveillance), EPIC: Hemisphere and EPIC v. DEA (Hemisphere FOIA).
