in the summer of 2016:

CIA Director John Brennan convened a secret task force at CIA headquarters composed of several dozen analysts and officers from the CIA, the NSA and the FBI…It functioned as a “sealed compartment” hidden even from the rest of the U.S. intelligence community; a unit whose workers were all made to sign additional non-disclosure forms.”

They worked exclusively for two groups of “customers,” officials said. The first was Obama and fewer than 14 senior officials in government. The second was a team of operations specialists at the CIA, NSA and FBI who took direction from the task force on where to aim their subsequent efforts to collect more intelligence on Russia.

The article said that initially, only four senior officials were allowed access to the Russian investigation intelligence. This group included Brennan, then-Director of National Intelligence James Clapper, then-Attorney General Loretta Lynch and then-FBI Director James Comey.

Gradually, the circle widened to include Vice President Biden and others. Agendas sent to Cabinet secretaries — including John F. Kerry at the State Department and Ashton B. Carter at the Pentagon

BARR:

It was sort of an ad hoc, small group — and most of these people are no longer with the FBI or the CIA or the other agencies involved. I think there’s a misconception out there that we know a lot about what happened. The fact of the matter is, Bob Mueller did not look at the government’s activities.
