Under Diggs’ tenure, the office also worked with the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) to launch Operation Texas Kill Switch. This operation targeted illegal machine gun conversion devices, resulting in multiple prosecutions. The district also secured major convictions, including a 25-year sentence for a Colombian drug trafficker and the extradition of the leader of the Los Pochos drug trafficking organization.
The civil division, under Diggs’ leadership, also saw notable successes. The office negotiated a $97 million settlement with Walgreens, resolving allegations that the company had improperly billed government payors for prescriptions that were never dispensed. Another major settlement of $21.75 million was reached with Medisca Inc. over claims that the company had submitted false and inflated average wholesale prices for ingredients used in compounded prescriptions.
Diggs’ resignation comes amid a broader wave of U.S. attorneys stepping down, following the approach of President Trump’s second term. Alamdar S. Hamdani, the U.S. Attorney for the Southern District of Texas, announced his resignation for Jan. 19, and other U.S. attorneys, including Jill E. Steinberg from the Southern District of Georgia and Peter D. Leary of the Middle District of Georgia, have also announced departures. Matthew Graves, the U.S. Attorney for the District of Columbia, who led the federal investigation into the January 6, 2021, Capitol attack, will also step down on Jan. 16.
