President Donald Trump warns that nations defying U.S. interests or the Supreme Court tariff ruling could face significantly higher tariffs without congressional approval.
On Feb. 23, President Donald Trump declared on Truth Social that countries undermining American interests or challenging a recent Supreme Court ruling on tariffs risk facing substantially higher duties or other consequences. He asserted that, as president, he does not require congressional approval to impose such tariffs. The statement reinforces his administration’s hardline approach to trade policy enforcement.
