Glenn Greenwald has revealed what he described last month as “the most important in the archive” of documents leaked by former NSA contractor Edward Snowden. The Intercept reports that the NSA and FBI have been spying on law-abiding Muslim-Americans — including lawyers, academics, civil rights activists, and a political candidate — possibly without warrants, under the pretext of the Foreign Intelligence Surveillance Act. The new document marks the first time individual US citizens have proof that they have been targeted by domestic surveillance, and could give them the legal standing to sue the government. The Intercept has been able to identify five targets from an NSA spreadsheet that lists thousands of suspects. The targets, all Muslim-Americans, include Faisal Gill, who was an advisor for the Bush administration’s Department of Homeland Security, and more.
