CBS News learned Thursday that the information National Security Agency leaker Edward Snowden has revealed so far is just a fraction of what he has. In fact, he has so much, some think it is worth giving him amnesty to get it back.
Rick Leggett is the man who was put in charge of the Snowden leak task force by Gen. Keith Alexander, who heads the NSA. The task force's job is to prevent another leak like this one from happening again. They're also trying to figure out how much damage the Snowden leaks have done, and how much damage they could still do.
Snowden, who is believed to still have access to 1.5 million classified documents he has not leaked, has been granted temporary asylum in Moscow, which leaves the U.S. with few options.
