CIA Director Haspel and the Anti-Trump Conspirators https://www.gatestoneinstitute.org/16597/gina-haspel-trump-conspirators#.X3sNqUl-3oc.twitter

That is the same timeframe when the FBI approached foreign policy academic and "utility government operative" Stefan Halper to begin the operation targeting Page and Papadopoulos in an FBI-designed foreign counterintel op, against Team Trump, to be launched in Cambridge, England.

Because the various intelligence agencies are sensitive, they do not use the word "approved." Instead, they use the word "coordinated." Jargon aside, nothing would have happened without Haspel's okay.

Who appears to have been "in on it" from Day One? Gina Haspel.
The FBI is not allowed to penetrate and subvert a presidential campaign. Executive Order 12333, Section 2.9, "Undisclosed Participation in Organizations in the United States," prohibits it in plain language...

That legal prohibition is the reason the FBI felt the need to manufacture a "foreign counterintelligence threat" in the UK and then "import" the investigation back into the United States.
