Grand Jury proceedings are controlled by the US Attorneys, and when they involve congress people, the DOJ. Look for the connection somewhere in the department of justice above the USA level, my guess, whomever is in charge of public integrity or even higher like at the deputy attorney general level or over the at FBI like in whom was running the ship over there as in McCabe. Someone had a hook into the dems to pass on the warning.
Are the Wasserman name connections in the office of the DOJ doing the prosecution all coincidental? George Webb has a new one today. The lead prosecutor named Michael John Marando is married to a Joanna Wasserman. No relationship to Steve Wasserman or Medussa Wasserman has been established.
