What would have prevented Hussein on the morning of Jan 20 2017 from issuing pardons to a raft of cabal minions and even himself, with no public notice? Absolutely nothing, and he would have been an idiot if he didn't.
Assuming Rosenstein's federal crime slate was wiped clean, how was Trump and Sessions to bring him to justice? By putting him in the position of signing the two post-inaugural renewals of the fraudulent Carter Page FISA warrant on behalf of the DOJ. Normally that responsibility would have fallen to Sessions, but he was recused from anything related to the Russia investigation. Gee, funny how that worked out!
Now Rosenstein has been trying to make a last-minute pitch to Trump to not declass parts of the FISA warrant and expose his culpability, but Trump won't see him. He's toast, and he did it to himself in service of a cabal which holds itself above the Constitution and rule of law, and he had the opportunity to do it to himself because that was the intention of Sessions and Trump.
Your simple explanation is the best one yet. I also suspect that secret pardons were put into place. POTUS choose not to release the information, rather allowed the system to work against those that were trying their best to do him in. Mr. Sessions has a judicial history of keeping his work very close to his vest with devastating results.
That's an interesting post, but this one item confuses me. Back in early 2017, why would there be a need to bring Rosenstein to justice? Had he committed some kind of crime before that?
