President Donald Trump says he is nominating Lance Schroyer as the next director of Immigration and Customs Enforcement.

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.

The Trump administration says a former executive at a private prison operator will serve as the acting head of U.S. Immigration and Customs Enforcement.
