In a recently concluded Freedom of Information Act lawsuit, EPIC tried to obtain legal analysis concerning the controversial PRISM surveillance program. The Justice Department responded that "no responsive records" exist. An earlier FOIA case brought by EPIC revealed that the Office of Legal Counsel provided advice on the warrantless wiretapping program of President Bush. But apparently no similar memos exist on the legality of the mass collection of Internet traffic by the NSA. For more information, see EPIC v. DOJ (PRISM).
