President Donald Trump said Saturday he is raising the worldwide tariffs on goods entering the United States from 10 percent to 15 percent "effective immediately," a day after the Supreme Court largely struck down his sweeping duties.

Trump said on his Truth Social platform that after a thorough review of Friday's "extraordinarily anti-American decision" by the court to rein in his tariff program, the administration was hiking the import levies "to the fully allowed, and legally tested, 15% level."
