I no longer believe President Trump (or any other President) has enough power to compel his own Justice Department to do their jobs. He still has the awesome power of the bully pulpit - and his own big mouth - and he is using both well enough to terrify the Deep State, but actual law enforcement is going to remain impossible to achieve when the “controlling legal authorities” have been so thoroughly subverted.
Trump has spent the last 21 months building his political capital, so that he can use his constitutional powers, to rein in the Deep State at the DOJ and FBI.
Trump has said that at some point he will get involved with his DOJ and FBI.
Hopefully it's after the election.
