President Donald Trump on Monday warned that the United States would face trillions in repayment costs should the Supreme Court rule against his imposition of tariffs.

The Supreme Court heard oral arguments over Trump's authority to impose tariffs last year, though it has yet to issue a decision on the case. Trump invoked the International Emergency Economic Powers Act (IEEPA) when issuing his "Liberation Day" tariffs, leading to challenges over the scope of his authority. The timeline for a final ruling is unclear, but it is expected in the near future.

"The actual numbers that we would have to pay back if, for any reason, the Supreme Court were to rule against the United States of America on Tariffs, would be many Hundreds of Billions of Dollars, and that doesn’t include the amount of 'payback' that Countries and Companies would require for the Investments they are making on building Plants, Factories, and Equipment, for the purpose of being able to avoid the payment of Tariffs," Trump warned on Truth Social. 

"When these Investments are added, we are talking about Trillions of Dollars! It would be a complete mess, and almost impossible for our Country to pay," he went on. "Anybody who says that it can be quickly and easily done would be making a false, inaccurate, or totally misunderstood answer to this very large and complex question."

"It may not be possible but, if it were, it would be Dollars that would be so large that it would take many years to figure out what number we are talking about and even, who, when, and where, to pay. Remember, when America shines brightly, the World shines brightly," he continued. "In other words, if the Supreme Court rules against the United States of America on this National Security bonanza, WE’RE SCREWED!"

Earlier in January, Trump announced that his administration had collected or would soon collect roughly $600 billion in tariff revenue since his return to the White House.
