House Intelligence Committee Chairman Rep. Mike Rogers, R-Mich., right, accompanied by the committee's ranking member Rep. C.A. Dutch Ruppersberger, D-Md., inform reporters about proposed changes to the National Security Agency’s program of sweeping up and storing vast amounts of data on Americans' phone calls, Tuesday, March 25, 2014, during a news conference on Capitol Hill in Washington. Details of the government's secret phone records collection program were disclosed last year by former NSA systems analyst Edward Snowden. Privacy advocates were outraged to learn that the government was holding onto phone records of innocent Americans for up to five years. Obama promised to make changes to the program in an effort to win back public support. (AP Photo/J. Scott Applewhite)
