If Mueller needs a scape goat, I would imagine that it would be Carter Page or Paul Manafort, but messing with Manafort could bring down the whole ‘rat’ party...this guy doesn't mess around...he knows people that know people that know people and Mueller could have the whole ‘rat’ party including himself all over the internet and world wide headlines on pizza gate, child and adult trafficking, how Bami got all that money to Iran, who forged Bambi's papers to get into this country as a ‘foreign exchange’ student...that's all Bami is and always has been, remember he was BORN in KENYA...
So maybe Mueller will want to keep his secrets quite, surely there are some RINO’s like Ryan, McConnell, Graham, McCain that don't want ALL of their dirty laundry world known...
