Per NBC News:

The legal challenge, led by Arizona Attorney General Kris Mayes and Oregon Attorney General Dan Rayfield, seeks to halt the enforcement of the global tariffs Trump levied that invoked a wartime law granting presidents the power to oversee trade if the United States is in a state of emergency.

“By claiming the authority to impose immense and ever-changing tariffs on whatever goods entering the United States he chooses, for whatever reason he finds convenient to declare an emergency, the President has upended the constitutional order and brought chaos to the American economy,” said the complaint Democratic attorneys general filed in the U.S. Court of International Trade.

Mayes said in a statement announcing the lawsuit, “Trump’s insane tariff scheme is not only economically reckless — it is illegal.”

New York Attorney General Letitia James, a frequent target of Trump’s attacks, argued that the tariffs “will lead to more inflation, unemployment, and economic damage” and that U.S. consumers will be forced to foot the bill for what amount to high import taxes.

In response to a request for comment, White House spokesman Kush Desai said: “Once again, Democrats like Letitia James are prioritizing a witch hunt against President Trump over protecting the safety and wellbeing of their constituents.”

“The Trump Administration remains committed to using its full legal authority to confront the distinct national emergencies our country is currently facing—both the scourge of illegal migration and fentanyl flows across our border and the exploding annual U.S. goods trade deficit,” Desai added.

From the Associated Press:

The states listed as plaintiffs in the lawsuit were Oregon, Arizona, Colorado, Connecticut, Delaware, Illinois, Maine, Minnesota, Nevada, New Mexico, New York and Vermont.

In a release, Arizona Attorney General Kris Mayes called Trump’s tariff scheme “insane.”

She said it was “not only economically reckless — it is illegal.”

Connecticut Attorney General William Tong said “Trump’s lawless and chaotic tariffs are a massive tax on Connecticut families and a disaster for Connecticut businesses and jobs.”

The lawsuit maintained that only Congress has the power to impose tariffs and that the president can only invoke the International Emergency Economic Powers Act when an emergency presents an “unusual and extraordinary threat” from abroad.

“By claiming the authority to impose immense and ever-changing tariffs on whatever goods entering the United States he chooses, for whatever reason he finds convenient to declare an emergency, the President has upended the constitutional order and brought chaos to the American economy,” the lawsuit said.
