Yes, the DOJ is rotten to the core. Trump was a fool to walk in and leave people like Rod Rosenstein & Andrew McCabe there. He should have looked at everyone who was involved in letting Clinton walk on the email crimes, and replaced every single one of them.
He was listening to insiders like Reince Preibus. He thought they were experienced bureaucrats that were looking out for him. They are all swamp rats and only looking out for themselves.
