Controversies over the National Security Agency's phone records and Internet snooping, and self-proclaimed leaker Edward Snowden, present some in Congress with a dilemma.

When Edward Snowden came forward as having leaked information about a National Security Agency program, he was quickly labeled a "whistle-blower" by many. Is that a misnomer?

Edward Snowden has said he may seek asylum in Iceland. Getting there from Hong Kong, to which he has fled, may not be possible. But Iceland has intervened before to offer safe haven to someone wanted in the U.S. Chess champion Bobby Fischer spent his last years there.

The Guardian has identified its source for a series of reports it published in recent days on secret U.S. surveillance activity. The paper says the source is Edward Snowden, a former technical assistant for the CIA who now works for a private-sector defense and technology consulting firm.

The Utah Data Center, 26 miles south of Salt Lake City, will begin operations in September. Though the NSA director has said it won't hold data on U.S. citizens, privacy advocates worry about the agency's expanding capabilities.

The Guardian says a former technical adviser for the CIA who now works for a defense and technology consultancy is responsible for the leaks.

Edward Snowden, 29, a contractor for the National Security Agency, says he's behind the leak of information on the NSA's surveillance program. Glenn Greenwald, the Guardian reporter who broke the story of the leak and of Snowden's identity, offers his insight.

Gen. Michael Hayden tells NPR that the NSA's surveillance activities are "perfectly legal" and a good balance between security and privacy.

Few people know how the National Security Administration works like Gen. Michael Hayden, who once served as head of the secretive organization. Host Rachel Martin talks with Hayden about recent revelations about the agency's access to phone and electronic communications.
