SWC begins with the question several have commenters raised here: Why? Why did the FBI interview Steele? I speculated that Comey and the top levels of the FBI needed to be on solid ground as they proceeded with their coup attempt against a recently inaugurated president. As SWC puts it:
Let’s begin with the fact that Danchenko did not just walk into an FBI building, show his driver’s license and say “I’m Igor Danchenko. I was Christopher Steele’s primary source on his Steele Dossier memos about President Trump. I’d like to talk with someone about what I said to Mr. Steele.”
However, SWC's conclusion is even more pointed than mine: FBI Interview of Christopher Steele’s Primary Sub-Source Was To Prepare for Him To Work Directly With Crossfire Hurricane Team.
Now, that scenario might be one thing, if the FBI had, like, just a bit of predication for Crossfire Hurricane. Of course, we all know that they didn't. And you may recall that I've always maintained that, in spite of the FBI's nonsensical claim that CH was predicated on the Downer - Papadopoulos chat, the real "predication" for CH was always the Steele dossier. By going with the Papadopoulos story they were simply steering clear of Steele's connections to the Clinton campaign.
SWC takes a closer look at just how Danchenko figured in the Horowitz Report, and what he comes up with feeds directly into that.

Before the election:
