DHS's Office of Inspector General found that fentanyl seizures by Homeland Security Investigations plummeted 39% between fiscal years 2024 and 2025, while the number of fentanyl investigations fell by 24%. The number of hours the agency spent on combating fentanyl dropped by nearly a third. The inspector general, which serves as DHS's official watchdog, said in the Aug. 20 report that the reason for the drop in fentanyl cases inside HSI was clear: "As ICE shifted priorities toward immigration enforcement, HSI's level of effort on fentanyl declined."
