FILE – This May 29, 2019 file photo released by U.S. Customs and Border Protection (CBP) shows some of 1,036 migrants who crossed the U.S.-Mexico border in El Paso, Texas, the largest that the Border Patrol says it has ever encountered. The federal government is opening a new mass shelter for migrant children near the U.S-Mexico border and is considering housing children on three military bases to add 3,000 more beds to the overtaxed system in the coming weeks.
