Sessions ala Rogers can / must be (only) involved as a witness IMO
Aha, witnesses.
That would totally explain it, remember reading that before. If Sessions not Trump’s “lapdog”, much more digestible for the gen. pub.
I think Rogers is the Final authority. He knew what happened. he pointed it out. Now he has to stay clear and Impartial. He is going to backup “everything” that Flynn is going to expose. Flynn is doing his job well. Half the people will not believe him but Rogers will seal the deal.
