The Trump administration refused to allow hundreds of migrant children whom it had separated from their parents at the southern border to return to their home countries with their family and deceived the public about reunification efforts, according to government auditors.

The Department of Homeland Security’s Inspector General’s Office concluded Monday that 348 children were left in the United States after their parents were flown out of the country despite the parents having requested they be reunited and returned as a family. The findings validated the claims that migrant adults had made at the time, alleging that Immigration and Customs Enforcement did not allow them to bring their children when they were deported despite Trump officials’ claims otherwise.
