But did they ever tell the FISA Court (FISC)?
Anonymous sources, including one in DoJ, are now telling us that the FBI "had doubts" about the Russian source for Christopher Steele's "dossier." The NYT reports:
By January 2017, F.B.I. agents had tracked down and interviewed one of Mr. Steele’s main sources, a Russian speaker from a former Soviet republic who had spent time in the West, according to a Justice Department document and three people familiar with the events, who spoke on the condition of anonymity. After questioning him about where he’d gotten his information, they suspected he might have added his own interpretations to reports passed on by his sources, one of the people said. For the F.B.I., that made it harder to decide what to trust.
Agents did not believe that either the source or Mr. Steele was deliberately inventing things, according to the former official. How the dossier ended up loaded with dubious or exaggerated details remains uncertain, but the document may be the result of a high-stakes game of telephone, in which rumors and hearsay were passed from source to source.
Another possibility — one that Mr. Steele has not ruled out — could be Russian disinformation.
Let's go step by step.
By January, 2017, FBI agents had "tracked down" one of Steele's "main sources." Really? Tracked down ... how? Pardon my skepticism, but I think a proper translation of this narrative would run something like this ...
By January, 2017, the FBI had finally persuaded Steele to allow them to speak to someone whom he claimed was a source of information for his dossier. In other words, by that point in time Steele had worked out a story with a Russian he knew, had rehearsed it, and thought it might work for purposes of an interview. And who was this dynamite source, who could pass on what Westerners were meeting with which Putin insiders? "A Russian speaker from a former Soviet republic who had spent time in the West." That's not very impressive as sources go, even allowing for protection of the "source's" identity.
But then they drop a real bombshell--this source, this "Russian speaker from a former Soviet republic who had spent time in the West," turns out to have been passing on tittle tattle from other "sources." And of course neither the FBI nor Steele would, even accepting that this was true, have access to those sources--who may or may not have ever existed. Obviously Steele must be a big John le Carre fan, since this reads exactly like the "source Merlin" setup in Tinker, Tailor, Soldier, Spy--with Steele, appropriately enough, playing Bill Haydon, the Russian "mole."
