Journalist In US Surveillance Case: More To Come [VIDEO]
A British journalist says the American defense contractor who exposed secret U.S. surveillance programs provided him with documents he hasn't yet written about.
Journalist Glenn Greenwald of The Guardian says more revelations should come out over the next several weeks and months.
"We are working on stories right at this moment that we think are very valuable for the public to know that don't in any way harm national security but that shine a light on this extremely secretive though momentous agency," he told CNN's Christiane Amanpour.
Greenwald's reports last week exposed the U.S. government programs to collect telephone and Internet records.
Snowden's whereabouts unknown
The American defense contractor who leaked information about classified U.S. surveillance programs is in Hong Kong, but the exact whereabouts of 29-year-old Edward Snowden are not known.
He checked out of a Hong Kong hotel and is still in semiautonomous Chinese territory according to the Guardian.
Meanwhile, the Justice Department is investigating whether Snowden's disclosures are a criminal offense. Snowden told the Guardian that he walked away from a 6-figure job and his family in Hawaii to reveal the extent of the NSA's information gathering.
Advocates say if Snowden is forced to return to the U.S. to face charges, they'll raise money for his legal defense.
Meanwhile, the European Parliament planned to debate the spy programs Tuesday and whether they have violated local privacy protections. EU officials in Brussels pledged to seek answers from U.S. diplomats at a trans-Atlantic ministerial meeting in Dublin later this week.
The global scrutiny comes after revelations from Snowden, who has chosen to reveal his identity. Snowden has fled to Hong Kong in hopes of escaping criminal charges as lawmakers including Senate intelligence chairwoman Sen. Dianne Feinstein of California accuse him of committing an "act of treason" that should be prosecuted.
Officials in Germany and the European Union issued calm but firm complaints Monday over two National Security Agency programs that target suspicious foreign messages — potentially including phone numbers, email, images, video and other online communications transmitted through U.S. providers. The chief British diplomat felt it necessary to try to assure Parliament that the spy programs do not encroach on U.K. privacy laws.
And in Washington, members of Congress said they would take a new look at potential ways to keep the U.S. safe from terror attacks without giving up privacy protections that critics charge are at risk with the government's current authority to broadly sweep up personal communications.
"There's very little trust in the government, and that's for good reason," said Rep. Adam Schiff, D-Calif., who sits on the House Intelligence Committee. "We're our own worst enemy."
