A group of business organizations and conservative lawyers are preparing to file a legal challenge against President Donald Trump's tariffs, asserting that he lacks the legal authority to impose them. Sources familiar with the effort indicate that the lawsuit could be filed as soon as Friday. A prominent conservative legal figure close to the president predicts that the Supreme Court would likely find the tariffs unconstitutional. The New Civil Liberties Alliance, a legal nonprofit, has already filed a complaint on behalf of a small stationery company in Florida, challenging the legality of the tariffs. The tariffs, including a 10% levy on global goods and higher rates on imports from China and other nations, have faced criticism from conservative legal scholars who argue that the president may have overstepped his delegated authority.
