The ruling is a major setback for Trump. The Supreme Court dealt a major blow to President Trump’s economic policy and ruled that he had exceeded his authority when he imposed tariffs on nearly every U.S. trading partner. The 6-3 decision, written by Chief Justice John G. Roberts Jr., has significant implications for the economy and consumers. The federal government has collected more than $200 billion in tariffs since the start of last year. Before the decision, the administration had said that a loss in the case could force the government to unwind trade deals with other countries and potentially pay tens of billions of dollars in refunds.

Gov. Gavin Newsom of California, a Democrat whose state had sued the federal government over the tariffs, called on President Trump to issue tariff refund checks to Americans. “These tariffs were nothing more than an illegal cash grab that drove up prices and hurt working families, so you could wreck longstanding alliances and extort them,” Newsom said, addressing Trump in a statement. “Every dollar unlawfully taken must be refunded immediately — with interest. Cough up!”

Trump will hold a press conference at 12:45 p.m. Eastern today to discuss the court’s ruling, Karoline Leavitt, the press secretary, announced on social media.
