S. Hrg. 113-365: The Surveillance Transparency Act of 2013, Hearing Before the Subcommittee on Privacy, Technology and the Law of the Committee on the Judiciary, United States Senate, First Session, November 13, 2013 [open pdf - 4MB]
This is from the November 13, 2013 hearing on "The Surveillance Transparency Act of 2013," held before the U.S. Senate Committee on the Judiciary. From the opening statement of Al Franken: "For months now, there has been a steady stream of news stories about the NSA's [National Security Agency] surveillance programs. And yet right now, by law, Americans cannot get really the most basic information about what is going on with these programs. Consider this: It has been months since the PRISM [Procurement Information System for Management] program and the telephone call records program were revealed to the public. And yet to this day, Americans do not know the actual number of people whose information has been collected under those programs; they do not know how many of those people are American; and they have no way of knowing how many of these Americans have had their information actually seen by government officials--as opposed to just being held in a database. The administration has taken good steps in good faith to address this problem. […] I have written a bipartisan bill to address this. It will require that the NSA disclose to the public how many people are having their data collected under each key foreign intelligence authority. It would make the NSA estimate how many of those people are American citizens or green card holders and how many of those Americans have had their information actually looked at by government agents." Statements, letters, and materials submitted for the record include those of the following: Dean Heller, Robert S. Litt, Kevin S. Bankston, Paul Rosenzweig, Richard Salgado, and Keith B. Alexander.
