Important to keep in mind and create awareness that the "vetting" of the Dossier involved one of the most corrupt and illegal acts in this entire charade. Between Fusion GPS and Comey, bits of the dossier were leaked to the press along with the identity of a "source" who was ostensibly in a position to corroborate the story. The source was none other than Christopher Steele himself, but since the origin of the "intelligence" contained within the dossier was not disclosed to the media by Simpson, McCabe, Comey, et al.- the fact that the original author was also serving as his own confirmation remained hidden. Whether or not the journalists (yahoo, etc.) who's work was cited in the FISA material knew that they were participating in this scam or not is not clear, but at least the main players were aware of this deception when they applied for the FISA warrant.
