Contained within Monday's FISA report by the DOJ Inspector General is the revelation that Fusion GPS, the firm paid by the Clinton campaign to produce the Steele dossier, "was paying Steele to discuss his reporting with the media." (P. 369 and elsewhere)
And when did Steele talk with the media (which got him fired as an FBI source)? September of 2016, roughly six weeks before the election.
One of the more damaging articles to result from these meetings was authored by Yahoo News journalist Michael Isikoff, who said in an interview that he was invited by Fusion GPS to meet a "secret source" at a Washington restaurant.
That secret source was none other than Christopher Steele, a former MI-6 Russia expert who fed the Isikoff information for a September 23, 2016 article - which would have had far greater reach and impact coming from such a widely-read media outlet vs. $100,000 in Russian-bought Facebook ads.
Isikoff's article claimed that former Trump campaign aide Carter Page "has opened up private communications with senior Russian officials - including talks about the possible lifting of economic sanctions if the Republican nominee becomes president."
This allegaton was found by special counsel Robert Mueller report to be false. Moreover, the FBI knew about it in December, 2016, when DOJ #4 Bruce Ohr told the agency as much.
