The Obama administration on Wednesday released formerly classified documents outlining a once-secret program of the National Security Agency that is collecting records of all domestic phone calls, as a newly leaked NSA document surfaced showing how the agency spies on Web browsing and other Internet activity abroad. Simultaneously, The Guardian published a still-classified 32-page presentation leaked by Snowden that describes the NSA's XKeyscore program, which mines Internet browsing information that the agency is apparently vacuuming up at 150 network sites around the world.
