Don't hold your breath. Barr is part of the swamp. He is chest pounding, and that is all. Just one more gorilla who will do nothing.
With the virus, I say it is 50/50 that Trump wins. So, there are but months to make something happen, and rest assured, if the Dems win POTUS in November, nothing will happen.
Barr and Company could not move slower. What does that tell you?
