New Mexico Gov. Michelle Lujan Grisham spoke alongside local, state and law enforcement officials Monday to announce that they plan to pursue restitution from the federal government over allegations that U.S. Drug Enforcement Administration officials knowingly let fentanyl shipments into New Mexico.

Mayors, district attorneys and sheriffs from across New Mexico joined Lujan Grisham in condemning the federal government’s alleged actions, which were detailed in a whistleblower complaint first reported by the Albuquerque Journal and the Associated Press. In one instance, a whistleblower alleged that agents stood by while 1.8 million fentanyl pills were trafficked in hopes of catching higher-ranking dealers and suppliers down the line.
