USA Today reports: NSA leaker Edward Snowden says he took his job with the National Security Agency for the sole purpose of obtaining evidence on Washington’s cyberspying networks, the South China Morning Post reported Monday.

Snowden, who was in Hong Kong before fleeing to Moscow this weekend, told the newspaper that he sought a position as an analyst with the consulting firm Booz Allen Hamilton so he could collect proof about the NSA’s secret surveillance program ahead of planned leaks to the media.

“My position with Booz Allen Hamilton granted me access to lists of machines all over the world the NSA hacked,” he told the Post in a June 12 interview that was published Monday. “That is why I accepted that position about three months ago.”

In his interview with the Post, Snowden divulged information that he claimed showed hacking by the NSA into computers in Hong Kong and mainland China.

“I did not release them earlier because I don’t want to simply dump huge amounts of documents without regard to their content,” he said. “I have to screen everything before releasing it to journalists.”

Asked by the Post if he specifically went to Booz Allen Hamilton as a computer systems administrator to gather evidence of surveillance, he replied: “Correct on Booz.”

His intention was to collect information about the NSA hacking into “the whole world” and “not specifically Hong Kong and China,” he said.
