Central American migrants are seen inside an enclosure in El Paso, Texas, March 27, 2019. They were being held by U.S. Customs and Border Protection officers after crossing the U.S.-Mexico border and turning themselves in to request asylum. Under Trump administration policy, the migrants must be returned to Mexico and apply for U.S. asylum from there. Migrants who arrive in Arizona must be bused to El Paso and also taken to Mexico, a policy Bishop Edward Weisenburger of Tucson, Ariz., decried Dec. 2 for not protecting "vulnerable people" and for placing them "in significant danger."
