(NEXSTAR) – Some Democrats say businesses and consumers should get refunds after the Supreme Court struck down President Trump's tariffs imposed under the International Emergency Economic Powers Act. "These were lawless, and effectively it was an illegal tax, and I think the people that paid those illegal taxes should get a refund," Sen. Adam Schiff (D-Calif.) said. Schiff and other Senate Democrats signed onto the "Tariff Refund Act of 2026." It requires Customs and Border Protection to process all refunds with interest within six months. "I'm particularly interested in consumers who paid that tax. They paid most of it," Sen. Schiff said. Data from CBP shows tariffs under IEEPA brought in more than $130 billion. Senate Minority Leader Chuck Schumer sent a letter to Treasury Secretary Scott Bessent on Friday, demanding the administration process refunds, writing, "If this administration does not act, Congress will." But the Supreme Court didn't address any kind of system for refunds. What happens next, the administration says, is up to lower courts. "The Supreme Court has remanded it down to the lower court, and we'll wait and see what the lower court says," Bessent said. Secretary Bessent says even if refunds must go out: "What are they going to do with the money? This shouldn't be corporate welfare." At least one company, FedEx, says it will return any potential refunds to customers. FedEx is among more than 1,000 companies that have filed suit in the U.S. Court of International Trade to try to recoup costs from the tariffs.
