“[On July 8, 2013] the Association of Research Libraries (ARL), along with 22 other good-government groups, sent a letter to the US Department of Justice urging Attorney General Eric Holder to make public any reports by Inspector General Michael Horowitz regarding the collection of Americans’ telephone records under Section 215 of the USA PATRIOT Act. If the Office of the Inspector General has not previously conducted a full review of this program, the letter asks it to do so. Section 215 of the PATRIOT Act allows the FBI to apply to the Foreign Intelligence Surveillance Court (FISC) for an order requiring the production of any tangible thing that is relevant to an authorized investigation to collect foreign intelligence or to protect against international terrorism or clandestine intelligence activities. Serious questions have been raised by lawmakers and legal experts about whether the recently revealed program, under which telephone companies are ordered to produce all of the telephony metadata for all of their subscribers, is consistent with the purpose or even the letter of Section 215.”
