A dozen states have sued the Trump administration in the U.S. Court of International Trade to stop its tariff policy, saying it is unlawful and has brought chaos to the American economy.

New York Attorney General Letitia James and 11 others are alleging the president's tariffs were an illegally imposed tax hike.

President Trump argues his tough tariff approach is forcing countries to renegotiate their trade deals with the United States.

President Donald Trump said on Tuesday he has no plans to fire Federal Reserve Chairman Jerome Powell, but said he wants interest rates to be lower. "I have no intention of firing him," Trump told reporters in the Oval Office on Tuesday.
