Border Patrol agents apprehended 27,518 members of family units in December, the highest monthly total on record. That figure has steadily been climbing now for five months, even as Trump made stopping migrant caravans the centerpiece of his midterm election strategy and drove Washington into a partial government shutdown over funding for his border wall.
Those caravan members, most of whom have been trying to exercise their legal right to request asylum in the U.S., contributed to a third straight month of more than 60,000 migrants being detained at U.S. ports of entry and arrested in the vast stretches of border in between.
