Still haven’t found any mention of other grand juries related to Obama era scandals. It seems the most obvious to investigate would be FISC abuses. I think the tampering (if any) with evidence concerning the FBI 302’s on the Flynn interrogation will be open and shut. I've read that judge sullivan has no tolerance for prosecutor shenanigans.
Rod Rosenstein was the lead prosecutor in Maryland, in 2015, when he helped whitewash the first Uranium One investigation. Rosenstein ignored the informant, William Campbell, and gave plea deals to several non government, non Deep State players.
Three years later, Rod Rosenstein is now the acting AG on Uranium One matters. Rosenstein has put together mostly the same prosecutorial team, and they've indicted another non government, non Deep State player.
Sessions is recused on this Hillary connected matter. The Fox is in charge of the hen house.
I think the wait is for the IG report (Horowitz) for the FISA, 302, etc. stuff to hit the fan. Horowitz, while appointed by Obama, is a “White Hat” - he fought tooth & nail against the Obama administration when they denied him access to investigate where the FISA abuses were taking place. Also, I’ve followed Judge Sullivan via Judicial Watch cases that have come before him .... Flynn hit the lotto when his case ended up before Judge Sullivan. Sullivan is a really good judge & no friend of misbehaving government prosecutors, as you pointed out.
Trump attorney Jay Sekulow correctly asserted that "we would not and should not know" if grand juries have been convened. We've become so accustomed to illegal leaks by our adversaries over the years that we expect to be told everything. The Trump Administration and its Justice Department are determined to play by the rules.
