Migrants who illegally come across the U.S.-Mexico border and are apprehended by Border Patrol are not being tested for the coronavirus before being released from custody and allowed to travel across the United States, the Washington Examiner has learned.

“They aren’t tested at encounter. [Unaccompanied children] and family units are moved out of custody quickly. If they are infected and do not have obvious symptoms, they are sent out,” a senior Customs and Border Protection official told the Washington Examiner on Monday. The official is not a union member and spoke on the condition of anonymity.
