The National Security Agency is secretly providing data to nearly two dozen U.S. government agencies with a Google-like" search engine built to share more than 850 billion records about phone calls, emails, cellphone locations, and internet chats, according to classified documents obtained by The Intercept. The documents provide the first definitive evidence that the NSA has for years made massive amounts of surveillance data directly accessible to domestic law enforcement agencies. ICREACH [as the search engine is called] contains information on the private communications of foreigners and, it appears, millions of records on American citizens who have not been accused of any wrongdoing. Details about its existence are contained in the archive of materials provided to The Intercept by NSA whistleblower Edward Snowden. Earlier revelations sourced to the Snowden documents have exposed a multitude of NSA programs for collecting large volumes of communications. The NSA has acknowledged that it shares some of its collected data with domestic agencies like the FBI, but details about the method and scope of its sharing have remained shrouded in secrecy. ICREACH has been accessible to more than 1,000 analysts at 23 U.S. government agencies that perform intelligence work, according to a 2010 memo. Information shared through ICREACH can be used to track people's movements, map out their networks of associates, help predict future actions, and potentially reveal religious affiliations or political beliefs.
