The U.S. government has indefinitely closed the Lukeville border crossing in Arizona due to an influx of migrants from countries like Senegal, Bangladesh, and China. The closure aims to free up Customs and Border Protection officers to assist with transportation and support. However, critics, including Arizona Democratic Gov. Katie Hobbs, argue that this move could harm trade and tourism. The Lukeville area has become a popular spot for crossing the border due to its remote location and light Border Patrol staffing.
