 In June 2013, a copy of a top-secret warrant, issued by the court on April 25, 2013, was leaked to London's "The Guardian" newspaper by NSA contractor Edward Snowden.That warrant orders Verizon Business Network Services to provide a daily feed to the NSA containing "telephony metadata" – comprehensive call detail records, including location data – about all calls in its system, including those that occur "wholly within the United States, including local telephone calls".The Obama administration published on July 31, 2013 a FISA Court ruling supporting an earlier order requiring a Verizon subsidiary to turn over all of its customers' phone logs for a three-month period, with rules that must be followed when accessing the data.
