Almost 1,500 migrant children are unaccounted for after being placed with sponsors by the Department of Health and Human Services, according to a top HHS official's testimony on Thursday the New York Times reports.

The details: Acting assistant secretary of HHS' Administration for Children and Families, Steven Wagner, told the Senate homeland security subcommittee that the department learned of 1,475 missing kids after calling to check in with their sponsors. This comes as the HHS and Department of Homeland Security are working towards an agreement on "joint procedures" for handling unaccompanied children. They're a year past the agreed upon deadline, per the NYT.
