Starting walking now.
For reasons known to him, President Trump controls only the square he stands on in Washington D.C. Both the Department of State and the Department of Justice not openly defy him, they openly and overtly plot against him. It would not surprise me to learn that he ordered Barr to prosecute Comey and Muller and Barr told him, GFY.
They will drag this out until the Democrats take control again and say "We were going to prosecute, but....." We have been screwed again.
