During his four years as General Counsel at the FBI, Weissmann would have been interacting on a daily basis with FBI management at the very highest levels, certainly including the Director (Mueller, then Comey) and Deputy Director – with additional contact with the highest levels in all important Divisions. Beyond that, however, he would have been developing contacts throughout the Intelligence Community and with "foreign partners" – prominently including the British intelligence agencies. The appeal of having Weissmann "in the loop" of the Russia hoax is obvious – he would be a trusted contact with the top levels of the FBI and would have a wide range of other useful contacts.

But Weissmann's connections to the FBI would not have been the end of his usefulness. Weissmann was well known to be a Hillary Clinton partisan, and even attended the Clinton election night surprise wake. Just how extensive were Weissmann's contacts with the Clinton campaign? Here the waters are murky. Nevertheless, Weissmann is known to have had contacts with Mary Jacoby, the wife of Glenn Simpson, as well as with Simpson himself
