Trump imposes sweeping IEEPA tariffs on Liberation Day

President Trump declared a national emergency and imposed a 10% baseline tariff on nearly all imports, with higher reciprocal rates on dozens of countries, citing the International Emergency Economic Powers Act. He paired it with separate fentanyl-trafficking tariffs on Canada, Mexico, and China. The tariffs took effect without a vote in Congress, setting up the fight over whether IEEPA authorizes tariffs at all.
