“The President has directed Secretary Johnson to establish an interagency Unified Coordination Group to ensure unity of effort across the Administration in responding effectively to this humanitarian situation.

This effort, lead and coordinated by FEMA, is quickly marshalling resources across the government to provide humanitarian relief to affected children. Addressing the rising flow of unaccompanied children crossing our southwest border is an important priority of this Administration and the Department of Homeland Security.
