The Supreme Court is hearing arguments over President Trump’s authority to impose tariffs under a statute that gives the president “emergency” powers. Jennifer Hillman of the Council on Foreign Relations explains how the case tests the Constitution’s grant of trade powers to Congress and could trigger up to $100 billion in tariff refunds if the Court strikes the tariffs down. Former Treasury Secretary Larry Summers calls tariffs a “self-inflicted supply shock” that raises prices and slows growth. (Source: Bloomberg)
