The Supreme Court has struck down President Donald Trump’s far-reaching global tariffs, handing him a significant loss on an issue crucial to his economic agenda. Friday's 6-3 decision centers on tariffs he unilaterally imposed under an emergency powers law, including the sweeping “reciprocal” tariffs levied on nearly every other country. The Republican president has called the case one of the most important in U.S. history and said a ruling against him would be an economic body blow to the country. But legal opposition crossed the political spectrum, including libertarian and pro-business groups typically aligned with the GOP. Administration officials have said they expect to keep the tariff framework in place under other authorities.
