Snowden disclosures of FISA warrant and PRISM program details

Snowden disclosures of FISA warrant and PRISM program details The passage recaps already‑public information about a 2013 FISA warrant, Verizon billing records, and the NSA PRISM program that has been widely reported and analyzed. It contains no new names, transactions, or unpublished evidence, limiting its investigative usefulness. However, it does reference high‑level agencies (FBI, NSA, DOJ, DNI) and the FISA court, which retains some relevance for oversight inquiries. Key insights: Judge Roger Vinson issued a FISA warrant on April 25, 2013 ordering Verizon to provide 90 days of landline billing records to the FBI.; The FBI passed the warrant to the NSA, which obtained the records and used them in the PRISM surveillance program.; PRISM was authorized under Section 702 of FISA and required directives from the Attorney General and Director of National Intelligence, with quarterly DOJ reviews.
