From the Barr memo Q posted
Michigan, you don’t say:
“I am therefore directing the Assistant Attorney General for Civil Rights, Eric Dreiband, and Matthew Schneider; the U.S. Attorney for the Eastern District of Michigan, to oversee and coordinate our efforts to monitor state and local policies and, if necessary, take action to correct them. They should work not only with all Department ofJustice offices and other federal agencies, but with state and local officials as well.”
