SEATTLE (AP) — More than 1,600 people arrested at the U.S.-Mexico border, including parents who have been separated from their children, are being transferred to federal prisons, U.S. immigration authorities confirmed Thursday. They said they’re running out of room at their own facilities amid President Donald Trump’s crackdown on illegal immigration. The move drew condemnation from activists who said the detainees may have legitimate claims to asylum and don’t deserve to be held in federal prisons.
