The Trump administration has located thousands of unaccompanied migrant minors who were deemed untraceable, with a significant majority being identified through a door-knocking campaign carried out by the Office of Refugee Resettlement.

ORR is the Department of Health and Human Services office responsible for detaining unaccompanied migrant children after they cross the border and placing them with adult sponsors in the United States. But senior White House officials tell the Washington Examiner that, since January, the office has also “located, contacted, and updated case information” for 7,500 unaccompanied migrant children who were considered “lost” because of incomplete or inaccurate contact information originally provided at the time of their release to HHS.
