April 18th, 2016 NSA Director Rogers locks all FBI contractors out of the NSA database after it was discovered that 1000's of improper FISA (and probably illegal at the time . . . until Barry Obama signed an order giving intelligence information access to just about everybody under the sun and allowed unmasking details to go people like the U.S. ambassador to the UN for example, weird timing) searches had been done on specific citizens of the United States inside the NSA database. Likely FBI contractors with certain ties to Clinton campaign operatives (Hillary loves her FBI files). There were 10's of thousands of searches by FBI contractors that went well beyond compliance guidelines and involved a very concise group of individuals.
Certain specific FBI "contractors" at the time: Crowd Strike, Nellie Ohr, Daniel Richman James "SadComeyFace" Comey's BFF who was retroactively granted top secret clearance after Comey illegally gave him classified information.
And on and on and on down the Rabbit Hole we go . . .
