“Having familiarized myself with the new policy and its ramifications,” Richard Pilger wrote in an email to his colleagues, obtained on Monday by the New York Times, “I must regretfully resign from my role as director of the Election Crimes Branch.” 

The policy change mentioned by Pilger was outlined by Barr in a memo on Monday, with the AG arguing that it is “imperative that the American people can trust that our elections were conducted in such a way that the outcomes accurately reflect the will of the voters.”

Previously, the ECB would not take overt investigative steps until the election was over, its results certified and all recounts and other contests concluded, Barr wrote, but “such a passive and delayed enforcement approach can result in situations in which election misconduct cannot realistically be rectified.”

Barr’s new policy authorizes inquiries and reviews if there are “clear and apparently credible allegations” of irregularities that, “if true, could potentially impact the outcome of a federal election in an individual state.”
