(USA TODAY) -- The National Security Agency said Thursday that Edward Snowden sent supervisors only one e-mail when he worked there, and it did not protest the nature of NSA surveillance programs.
In the e-mail to the Office of General Counsel, Snowden posed a legal question about a training program.
"There are numerous avenues that Mr. Snowden could have used to raise other concerns or whistleblower allegations," the NSA said in a statement. "We have searched for additional indications of outreach from him in those areas and to date have not discovered any engagements related to his claims."
In an interview with NBC News, Snowden said he told the NSA about his concerns about its widespread methods of intelligence gathering.
"I actually did go through channels, and that is documented," Snowden said. "The NSA has records, they have copies of emails right now to their Office of General Counsel, to their oversight and compliance folks, from me raising concerns about the NSA's interpretations of its legal authorities. … The response more or less, in bureaucratic language, was, 'You should stop asking questions.'"
Snowden — who remains in Russia, which has granted him temporary asylum — faces espionage charges in the United States.
