President Trump threatened on Friday to close the southern border unless Mexico stops migrants from entering the U.S. illegally. “Mexico’s tough. They can stop ‘em, but they chose not to," he said. "Now they’re gonna stop ‘em. And if they don’t stop ‘em, we’re closing the border”. Among those people entering the country are children and teens. Now, new guidance is being offered to judges who work with newly arrived immigrant youth entering the juvenile justice system. Many of these young people have faced trauma – violence, separation from loved ones, and adjusting to life in a new culture. Dr. Julian Ford is a professor in the Department of Psychiatry at UConn Health and one of the authors of the guidance.
