Immigration and Customs Enforcement has been rapidly expanding its workforce, hiring thousands of new officers.

U.S. Immigration and Customs Enforcement is retreating from a plan to use warehouses to hold up to 10,000 people on a single site, jettisoning a key piece of former Homeland Security Secretary Kristi Noem’s $38-billion plan to rapidly expand detention capacity this year.

Contractors running Immigration and Customs Enforcement facilities can rely more heavily on artificial intelligence tools to communicate with detainees and continue refusing to pay wages for detainees’ “voluntary work."
