McALLEN, Texas (AP) — U.S. Immigration and Customs Enforcement says it deported more than 270,000 people over a recent 12-month period, the highest annual tally in a decade. Its report released Thursday illustrates some financial and operational challenges that President-elect Donald Trump will face to carry out his pledge of mass deportations. Deportations during the fiscal year ended Sept. 30 nearly doubled from the same period a year earlier. In a separate report, U.S. authorities said arrests for crossing the border illegally from Mexico in November fell 18% from a month earlier to the lowest level since July 2020.
