The Department of Homeland Security agency tasked with separating border children from parents who were referred for prosecution for illegal entry said Thursday it will immediately begin keeping verified family units together, in accordance with the executive order President Trump signed Wednesday.

“U.S. Customs and Border Protection has taken immediate steps to implement the President’s Executive Order Affording Congress the Opportunity to Address Family Separation,” CBP said in a statement. “Family unity will be maintained for families apprehended crossing the border illegally, and they will be transferred together to U.S. Immigration and Customs Enforcement.”
