Costco Joins Companies Suing Trump Administration Over Tariffs

Costco became the latest and one of the biggest companies to sue the Trump administration over tariffs in an effort to secure a full refund should the Supreme Court rule the sweeping duties illegal. 

In a filing with the U.S. Court of International Trade on Friday, Costco said the lawsuit is necessary to make sure it is eligible for refunds if the Supreme Court rejects the administration’s reasons for tariffs collected under the International Emergency Economic Powers Act. Costco executives declined to comment.
