Did the United States really lose track of 1,475 immigrant kids? In short, yes. During a Senate committee hearing late last month, Steven Wagner, an official with the Department of Health and Human Services, testified that the federal agency had lost track of 1,475 children who had crossed the U.S.-Mexico border on their own (that is, unaccompanied by adults) and subsequently were placed with adult sponsors in the United States. As the Associated Press reported, the number was based on a survey of more than 7,000 children: From October to December 2017, HHS called 7,635 children the agency had placed with sponsors, and found 6,075 of the children were still living with their sponsors, 28 had run away, five had been deported and 52 were living with someone else. The rest were missing, said Steven Wagner, acting assistant secretary at HHS.
