AUSTIN, Texas — Whether the Biden administration will be able to follow through on the Supreme Court’s order to restart a Trump administration program that made asylum-seekers temporarily live in Mexico will come down to whether Mexican President Andres Manuel Lopez Obrador allows it.

But the Mexican leader has yet to weigh in on the program, and other signs indicate that he may be dragging his feet. Reluctance on his part could prevent the reluctant Biden administration from having to follow through on the court order.
