Washington, June 24 (RHC) – US journalist Glenn Greenwald says he will soon disclose new documents revealing which kinds of citizens are targeted by Washington’s spying activities.

Greenwald, whose reporting of documents leaked by Edward Snowden helped expose the scope and scale of US spying activities, said Monday in an interview with MSNBC's Ronan Farrow that the document he intends to release is a "very imminent" report "on the question of what kinds of citizens are being targeted by the NSA."

He said he considered the report "the most important in the archive" of documents given to him by Snowden.

In his previous interviews, Greenwald had said that Snowden's documents include a list of the people, including dissidents and critics, the US government has been targeting.

"One of the big questions when it comes to domestic spying is, ‘Who have been the NSA’s specific targets?’ Are they political critics and dissidents and activists? Are they genuinely people we’d regard as terrorists? What are the metrics and calculations that go into choosing those targets and what is done with the surveillance that is conducted? Those are the kinds of questions that I want to still answer,” Greenwald told British newspaper The Sunday Times earlier this year.

Documents leaked by Snowden have shown, among other things, how the NSA collects phone records of all American citizens and tracks the use of US-based web servers by all people around the world.
