Bureau of Alcohol, Tobacco, Firearms and Explosives police officers are seen in Uvalde, Texas, May 25, 2022.
The U.S. Office of Special Counsel, which disclosed the mismanagement, said it had alerted President Joe Biden and Congress of "substantial waste, mismanagement, and unlawful employment practices" involving high-level jobs at ATF.
The Office of Special Counsel said that during a five-year period that officials investigated, 108 ATF employees who worked in non-law-enforcement jobs "were improperly provided Law Enforcement Availability Pay (LEAP) and enhanced retirement benefits."
In its official response to OSC, ATF contested claims about the designation of some of the positions being misclassified.
OPM later concluded that the ATF's leadership "demonstrated disregard for the rule of law and regulations" governing federal management policies and practices.
