Twenty-five US states sued President Donald Trump's administration Monday over its latest tariffs, saying they were a pretext for replacing import taxes struck down by the Supreme Court in February.

The United States imposed double-digit tariffs on 59 countries plus the European Union last month, accusing them of not doing enough to crack down on imports produced by forced labor.

The new tariffs took effect just as the clock ran out on temporary tariffs President Trump had turned to after the Supreme Court defeat.What did the 25 states say in their lawsuit against Trump tariffs?

"After losing at the Supreme Court, the administration is once again trying to illegally raise taxes on families and businesses with a new round of tariffs," said New York Attorney General Letitia James, launching the lawsuit.

"Despite losing every step of the way, Trump is trying yet again to inflict more on working families and homegrown businesses," added Oregon Attorney General Dan Rayfield.
