McALLEN, Tex. — The number of migrants crossing the U.S. southern border illegally has dropped more than 40 percent in the three weeks since President Biden announced broad restrictions on asylum claims, administration officials said Wednesday.

       U.S. agents have taken fewer than 2,400 migrants into custody per day over the past week, down from more than 3,800 at the beginning of June, according to the latest Department of Homeland Security data. That is the lowest level of illegal crossings since Biden took office, DHS said.
