Edward Snowden has challenged NSA (National Security Agency) to deny that he tried to use legal means to 'blow the whistle' before leaking the documents.
Snowden said that he tried to contact NSA via e-mails, and welcomed members of Congress to get a written letter from NSA in this context despite the fact that 'whistle-blower protection laws in the US do not protect contractors in the national security arena'.
According to Cnet, the challenge was made when NSA Deputy Director Rick Ladgett reportedly said that Snowden didn't make any formal complaints.
However, Snowden maintains that he tried to work within the system before leaking the documents.
