(CNN) The federal government has placed thousands of unaccompanied immigrant children in the homes of sponsors, but last year it couldn't account for nearly 1,500 of them.
Steven Wagner, a top official with the Department of Health and Human Services, disclosed the number to a Senate subcommittee last month while discussing the state of the Office of Refugee Resettlement (ORR) that oversees the care of unaccompanied immigrant children.
