On Thursday, James Clapper, the Director of National Intelligence, wrote "The Guardian and The Washington Post articles refer to collection of communications pursuant to Section 702 of the Foreign Intelligence Surveillance Act. They contain numerous inaccuracies."[1]
Today, he released a fact sheet[2] which stated, among other things,
* PRISM is not an undisclosed collection or data mining program. It is an internal government computer system used to facilitate the government’s statutorily authorized collection of foreign intelligence information from electronic communication service providers under court supervision, as authorized by Section 702 of the Foreign Intelligence Surveillance Act (FISA) (50 U.S.C. § 1881a). This authority was created by the Congress and has been widely known and publicly discussed since its inception in 2008.
* Under Section 702 of FISA, the United States Government does not unilaterally obtain information from the servers of U.S. electronic communication service providers. All such information is obtained with FISA Court approval and with the knowledge of the provider based upon a written directive from the Attorney General and the Director of National Intelligence. In short, Section 702 facilitates the targeted acquisition of foreign intelligence information concerning foreign targets located outside the United States under court oversight. Service providers supply information to the Government when they are lawfully required to do so.
* The Government cannot target anyone under the court-approved procedures for Section 702 collection unless there is an appropriate, and documented, foreign intelligence purpose for the acquisition (such as for the prevention of terrorism, hostile cyber activities, or nuclear proliferation) and the foreign target is reasonably believed to be outside the United States. We cannot target even foreign persons overseas without a valid foreign intelligence purpose.
* In addition, Section 702 cannot be used to intentionally target any U.S. citizen, or any other U.S. person, or to intentionally target any person known to be in the United States. Likewise, Section 702 cannot be used to target a person outside the United States if the purpose is to acquire information from a person inside the United States.
