US Supreme Court likely to rule on Trump’s tariffs today. What could happen?

The US Supreme Court is expected to rule on the legality of Trump's tariffs, which could impact $133.5 billion collected from importers. If the court rules against Trump, the US may have to refund up to $150 billion in tariffs, but the administration may seek alternative ways to maintain tariffs. A ruling in favor of Trump could expand presidential powers to impose taxes and tariffs under the IEEPA, raising concerns about executive authority.
