US President Donald Trump's sweeping tariff strategy has suffered one of its biggest legal and financial setbacks after the US Supreme Court struck down key tariffs imposed under the IEEPA. The landmark ruling concluded that the law did not grant the President unilateral authority to impose broad trade tariffs using emergency powers, dealing a major blow to one of Trump's signature economic policies. Following the verdict, the Trump administration has already returned nearly $100 billion in tariff collections to importers through the US Treasury, with US CBP confirming that refunds including interest have reached a major milestone. Court filings indicate that more than half of the invalidated tariff revenue has already been reimbursed, while additional payments are expected in the coming months. WATCH
