Casey went on to question whether such matters are an appropriate use of Western District resources, noting the particular impact of the opioid crisis in the state.

“Community leaders in Western Pennsylvania, including the United States Attorney’s Office, should be applauded for their efforts to reduce the opioid epidemic in the region,” Casey wrote. “Unfortunately, it is clear that as Western Pennsylvania has tried to close the door on the opioid crisis, more doors have opened for other types of illicit drug use and drug trafficking. Just recently, U.S. Attorney Brady commented on the need to fight the ‘fourth wave’ of the crisis after identifying an increase in incidents in Western Pennsylvania involving cocaine, crack methamphetamine.”

“Given these concerns, I urge you to take immediate steps to ensure that the DOJ does not continue diverting law enforcement resources away from the important law enforcement priorities in the Western District of Pennsylvania,” Casey concluded.
