President Donald Trump's across-the-board tariffs on goods from Mexico have not only left President Claudia Sheinbaum politically unscathed from likely economic damage but may strengthen her hand as Mexicans rally against perceived unfair treatment.

President Sheinbaum announced that Mexico will respond to the United States' 25% tariffs on its exports with "tariff and non-tariff measures."

As President Donald Trump pressures Mexico to address the flow of migrants and drugs heading north into the United States, the Supreme Court is set to hear arguments Tuesday in a major appeal about one thing that’s crossing the border toward Mexico: guns.
