New Mexico's Attorney General, Raúl Torrez, has challenged the federal government's denial of records related to DEA undercover operations that allegedly allowed fentanyl to reach Albuquerque streets. The records are part of a state investigation into allegations that the DEA allowed significant amounts of fentanyl to remain on New Mexico streets during undercover operations. Torrez has set an Aug. 17 deadline for the results and will take his efforts to U.S. District Court if ignored. The state argues that the federal denial improperly interpreted its own regulations governing requests for records and cited rules that do not apply in this case.
