DNI Clapper Declassifies Intelligence Community Documents Regarding Collection Under Section 501 of the Foreign Intelligence Surveillance Act (FISA) [September 10, 2013] [open pdf - 83KB]
From the Office of the Director of National Intelligence (ODNI): "In June of this year, President Obama directed me to declassify and make public as much information as possible about certain sensitive intelligence collection programs undertaken under the authority of the Foreign Intelligence Surveillance Act (FISA) while being mindful of the need to protect national security. Consistent with this directive, today I authorized the declassification and public release of a number of documents pertaining to the Government's collection of bulk telephony metadata under Section 501 of the FISA, as amended by Section 215 of the USA PATRIOT Act. These documents were properly classified, and their declassification is not done lightly. I have determined, however, that the harm to national security in these circumstances is outweighed by the public interest."
