Report on the Telephone Records Program Conducted under Section 215 of the USA PATRIOT Act and on the Operations of the Foreign Intelligence Surveillance Court [open pdf - 2MB]
"On June 5, 2013, the British newspaper 'The Guardian' published the first of a series of articles based on unauthorized disclosures of classified documents by Edward Snowden, a contractor for the National Security Agency ('NSA'). The article described an NSA program to collect millions of telephone records, including records about purely domestic calls. Over the course of the next several days, there were additional articles regarding this program as well as another NSA program referred to in leaked documents as 'PRISM.' […] In response to the congressional and presidential requests, the Board immediately initiated a study of the 215 and 702 programs and the operation of the FISA [The Foreign Intelligence Surveillance Act] court. This Report contains the results of the Board's 215 program study as well as our analysis and recommendations regarding the FISC's [Foreign Intelligence Surveillance Court] operation."
