A government audit of U.S. Immigration and Customs Enforcement found the agency may be missing chances to identify and detain known or suspected terrorists.
ICE is now working to strengthen and expand its screening process.
The U.S. Department of Homeland Security’s Office of Inspector General completed the audit.
DHS-OIG found at least one violation of ICE’s own screening process for identifying known or suspected terrorists in every case file it sampled.
DHS-OIG concluded the violations were due to limited program oversight and weak management controls.
ICE agreed with recommendations included in the audit, and is working to expand screening to include people who are under supervision, but not in ICE custody.
ICE also plans improve access to information at field offices, and bolster internal controls.
