Edward Snowden is expected to offer his opinion of President Obama's NSA reforms during a Webcast question-and-answer session on Thursday. It will be Snowden's first live chat since he began releasing classified internal documents last June that revealed the National Security Agency's surveillance programs, according to FreeSnowden.is, the support site hosting the hour-long Q&A. Snowden, who is currently living in exile in Russia, was charged with espionage after reportedly stealing 1.7 million classified documents from US government computers.
