Trump administration officials have admitted they don't yet know how they'll bring families separated at the Mexican border back together. "This policy is relatively new," said Steven Wagner, an acting assistant secretary at the Department of Health and Human Services. "We’re still working through the experience of reunifying kids with their parents after adjudication." Federal officials say there are hotlines to call and an email address for those seeking information, but advocates say those methods aren't working especially in cases where parents are illiterate and don’t know how to spell their children’s names. Additionally, Department of Health and Human Services officials don't give out any information if a child has been transferred out of a government shelter, including if the child has been deported. More than 2,000 minors have been separated from their families since May.
