EXCLUSIVE — House Republicans are pushing the Biden administration for information on the number of potentially dangerous adults in the United States who applied to take custody of unaccompanied migrant children in government custody after crossing the southern border alone.

Senior Republicans on the House Homeland Security Committee sent the Department of Health and Human Services a letter late Monday that requested data from its Office of Refugee Resettlement, which is responsible for caring for the more than 430,000 children in federal custody at the border and screening the adult sponsors the child is placed to live with, the Washington Examiner has learned.
