Trump administration sued by 22 state attorneys general over tariffs imposed without congressional approval

On March 5, 2026, a coalition of 22 state attorneys general and two governors filed a lawsuit in the U.S. Court of International Trade to block President Trump's latest round of tariffs, including a new 10 percent tariff on imports. The lawsuit argues that Trump's tariffs violate the Constitution's separation of powers principle, as Article I grants Congress—not the President—the power to impose tariffs and taxes. The coalition, led by New York Attorney General Letitia James and including Minnesota Attorney General Keith Ellison, contends the tariffs also violate the Administrative Procedure Act and will increase prices for American consumers and businesses. Attorney General Ellison noted he had previously sued Trump over illegal tariffs and won at the Supreme Court.
