As Trump pushes Supreme Court to uphold his tariffs, he signals trade deals will be defunct if he loses the case: 'I guess we'd have to unwind them'

""Our country has a chance to be unbelievably rich again. It could also be unbelievably poor again. If we don't win that case, our country is going to suffer so greatly, so greatly," Trump said."

""We made a deal with the European Union where they're paying us almost a trillion dollars," he added. "And you know what? They're happy. It's done. These deals are all done, I guess we'd have to unwind them.""

Legal challenges have called the authority for broad U.S. import tariffs into question. A federal appeals court ruled that invoking the International Emergency Economic Powers Act of 1977 to justify tariffs exceeded presidential authority and upheld a New York trade court decision. The administration asked the Supreme Court to review the ruling and requested a decision on whether to hear the case by Sept. 10. The tariffs had been presented as tools to deter illegal migration and fentanyl flows and to incentivize domestic manufacturing. Trade agreements with partners such as South Korea and the European Union were tied to tariff leverage and could be unwound if courts overturn the policy.
