Trump gave the responsibility to Barr. Be patient.
Not much else we can do at the moment. I just hope we eventually see some action and not just campaign sound-bites. Too often the politicians, and the DOJ/FBI would rather not rock the boat too much and prefer to sweep this all under the rug to be quickly forgotten. That we are already into the 2020 election cycle makes that so much more likely. I blame Sessions and all of the Obama holdovers.
