A journalist who worked with whistleblower Edward Snowden is set to reveal the names of individuals the American government has spied on.

Glenn Greenwald said in an interview with the New York Post, that this latest information, gathered from nearly two million documents Snowden stole from the government, would help shape the whistleblower’s legacy.

When discussing the people the US government surveilled, Greenwald asked: “Are they political critics and dissidents and activists? Are they genuinely people we’d regard as terrorists?”

“Those are the kinds of questions that I want to still answer.”

It has been almost one year since Greenwald first reported on Snowden’s leaked documents that outlined the US government’s spying tactics.

In an interview with GQ magazine, Mr Greenwald said that he had saved the best for last.
