Conspiracy ping!
Senator Grassley directly asked Session if Session had recused himself on all things Hillary and Sessions said he had. Then Grassley asked who was looking into U1? Sessions answered Rosenstein.
So I will believe my lying ears until Sessions himself says otherwise.
One more time. Why is Mueller not looking at how the DNC emails got to Wiki Leaks? That is at the heart of the Russia, Russia, Russia thing he was appointed to investigate.
