Small businesses that sued President Trump over his tariffs aren’t looking just to end them; they are also hoping to receive a refund from Uncle Sam to compensate for their losses over the past months. The Supreme Court is set to hear their case Wednesday in what is shaping up as one of the significant cases this term, testing the limits of the president’s powers. Michael McConnell, one of the attorneys for the five small businesses, said they have sustained serious setbacks since the president raised tariffs. One of the businesses is teetering on the brink of bankruptcy.
