A new policy that year, detailed in “Defense Supplemental Procedures Governing Communications Metadata Analysis,” authorized by Defense Secretary Robert M. Gates and Attorney General Michael B. Mukasey, said that since the Supreme Court had ruled that metadata was not constitutionally protected, N.S.A. analysts could use such information “without regard to the nationality or location of the communicants,” according to an internal N.S.A. description of the policy.
The documents show that significant amounts of information from the United States go into Mainway. An internal N.S.A. bulletin, for example, noted that in 2011 Mainway was taking in 700 million phone records per day. In August 2011, it began receiving an additional 1.1 billion cellphone records daily from an unnamed American service provider under Section 702 of the 2008 FISA Amendments Act, which allows for the collection of the data of Americans if at least one end of the communication is believed to be foreign.
The overall volume of metadata collected by the N.S.A. is reflected in the agency’s secret 2013 budget request to Congress. The budget document, disclosed by Mr. Snowden, shows that the agency is pouring money and manpower into creating a metadata repository capable of taking in 20 billion “record events” daily and making them available to N.S.A. analysts within 60 minutes.
