The Oval Office meeting this past March began, as so many had, with President Trump fuming about migrants. But this time he had a solution. As White House advisers listened astonished, he ordered them to shut down the entire 2,000-mile border with Mexico — by noon the next day.

Yet they also knew how much the president’s zeal to stop immigration had sent him lurching for solutions, one more extreme than the next.
