According to Brennan’s spokesman, Durham probed Brennan about the Intelligence Community Assessment (aka Obama’s Dossier.)

Some quick “Svetlana facts”.

-Brennan created “conclusions” which were later inserted into Obama dossier in August 2016 as Hillary was losing in polls. /1

-Brennan’s “conclusions” was based on “a source close to Putin” which, as I have previously shown, was nothing of the sort but most likely Halper lies laundered through Steele.
-Teflon man Obama wanted the other intel agencies to agree with Brennan before making a formal /2

announcement. Other agencies refused
-Brennan “shopped” his dossier as low down the food chain as Schiff
-After the election, a few weeks before Trump inauguration, Obama and Brennan stitched up a deal where 3 agencies (not 17 as were told) signed up to the Brennan-Obama dossier

Out of the three agencies, the only one that deals with objective intelligence, the NSA, gave it only a “moderate” level of confidence. Admiral Rogers snookered it.
-The other two “agencies” were in fact handpicked members of Brennan working group from the FBI and the CIA. /4

The centerpiece of Obama Dossier (ICA) is that Putin helped Trump win the election
Durham’s investigation is reportedly probing whether this was a genuine piece of intel or pre-packaged conclusion
The key conclusion was leaked to Wash Post just a few days into the ICA preparation
