Caleb Vitello, a veteran ICE official who was installed as acting director when Trump took office, will be reassigned.

ICE Director Caleb Vitello has been demoted as the Trump administration pushes for stricter immigration enforcement. Vitello, a 23-year ICE veteran, was reassigned after President Donald Trump expressed frustration over the slow pace of migrant arrests and deportations.

President Donald Trump signed an executive order Wednesday to bar undocumented migrants from accessing public benefits, even though they’re already denied most federally funded programs—his latest move to tamp down on illegal immigration, though it wasn’t immediately clear which initiatives would be impacted.
