An investigation is underway into Edward Snowden, the NSA contractor who revealed programs which collect data on Americans phone calls and the internet. Now Snowden may leak more information to the public.
Glenn Greenwald of "The Guardian" first published Snowden's story, and says the former NSA contractor has more significant revelations.
Greenwald, and his colleague Laura Poitras interviewed Snowden in Hong Kong where he was hiding out. Snowden told Greenwald, and Poitras he had access to many documents containing intelligence community secrets.
"I had access to, you know, the full rosters of everyone working at the NSA, the entire intelligence community and the entire undercover assets all around the world," Snowden said.
The US government has not charged Snowden with any crime, nor issued a warrant for his arrest. Lawmakers on Capitol Hill are divided about whether or not to prosecute Snowden.
California Senator Dianne Feinstein, head of the Senate Intelligence Committee, wants Snowden prosecuted.
"He violated the law. It's an act of treason in my view," said Senator Feinstein.
However, many others, like former Congressman Ron Paul, are praising Snowden.
In a statement Paul said Snowden, and Greenwald have "done a great service to the American people by exposing the truth about what our government is doing in secret."
Congress will learn more about the secret NSA surveillance programs Tuesday. The entire House of Representatives will receive a closed-door briefing on the subject from the NSA Tuesday afternoon.
