A second National Security Agency whistleblower exists within the ranks of government intelligence.
That bombshell comes toward the end of Citizenfour, a new documentary from filmmaker Laura Poitras about NSA informant Edward Snowden that had its world premiere on Friday at the New York Film Festival.
In the key scene, journalist Glenn Greenwald visits Snowden at a hotel room in Moscow. Fearing they are being taped, Greenwald communicates with Snowden via pen and paper.
While some of the exchanges are blurred for the camera, it becomes clear that Greenwald wants to convey that another government whistleblower — higher in rank than Snowden — has come forward.
