Migrants are rushing across the Mexico border in hopes of entering the U.S. in the final hours before pandemic-related asylum restrictions are lifted at midnight. Many migrants fear that the change could make it more difficult for them to stay. Late Thursday, however, the Biden administration was dealt a potentially serious legal setback when a federal judge temporarily blocked its attempt to more quickly release migrants when Border Patrol holding stations are full. With the late-night deadline looming, misinformation and confusion buffeted migrants as they paced the border at the Rio Grande, often unsure of where to go or what to do next.
