New Scoop from Greenwald/Snowden on NSA Online Snooping

UPDATE  Charlie Savage at NYT just out with major report, which also cites the new Greenwald:  "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 in the United States, as top officials testified before the Senate Judiciary Committee."

Just out at The Guardian, a big one.   And see key doc here.  

A top secret National Security Agency program allows analysts to search with no prior authorization through vast databases containing emails, online chats and the browsing histories of millions of individuals, according to documents provided by whistleblower Edward Snowden.

The NSA boasts in training materials that the program, called XKeyscore, is its "widest reaching" system for developing intelligence from the internet.

The latest revelations will add to the intense public and congressional debate around the extent of NSA surveillance programs. They come as senior intelligence officials testify to the Senate judiciary committee on Wednesday, releasing classified documents in response to the Guardian's earlier stories on bulk collection of phone records and Fisa surveillance court oversight.
