Trump admin live updates: Hegseth says admiral ordered 2nd strike on boat, as White House defends legality

While Americans were enjoying their Thanksgiving holiday, wholesale giant Costco filed a lawsuit against the Trump administration for a “full refund” for the tariffs the company paid.

“This separate action is necessary, however, because even if the [International Emergency Economic Powers Act] duties and underlying executive orders are held unlawful by the Supreme Court, importers that have paid IEEPA duties, including Plaintiff, are not guaranteed a refund for those unlawfully collected tariffs in the absence of their own judgment and judicial relief,” the lawsuit filed in the Court of International Trade on Friday said.

While most lawsuits against the tariffs come from small businesses, Costco is seeking a refund for the tariff payments they incurred. Congress, not the president, has the power to impose tariffs, the lawsuit said.

The Court of International Trade “have agreed the IEEPA duties are not authorized,” the lawsuit said.

This lawsuit is identical to other suits filed by American companies challenging the legality of Trump’s IEEPA tariffs — including one currently pending a decision at the U.S. Supreme Court.
