A group of 25 Democratic-led US states sued President Donald Trump's administration on Monday, arguing that its latest round of tariffs on goods from 60 trading partners goes beyond the president's legal authority to tax imports. The lawsuit, filed in the US Court of International Trade in New York, claims the new levies are an attempt to reimpose duties that courts have already ruled illegal. The states say the tariffs unlawfully replace measures struck down by the judiciary. The legal challenge follows lawsuits filed last month by small US businesses, which sought to block the same tariffs on the day they took effect. The new tariffs apply to goods from 60 US trading partners, including Canada. The states are asking the court to block the tariffs, arguing that only Congress has the power to impose such taxes.
