12 States Sue Trump Over His Tariffs (2025)

A dozen states, most of them led by Democrats, sued President Trump over his tariffs on Wednesday, arguing that he has no power to “arbitrarily impose tariffs as he has done here.”

Contending that only Congress has the power to legislate tariffs, the states are asking the court to block the Trump administration from enforcing what they said were unlawful tariffs.

“These edicts reflect a national trade policy that now hinges on the president’s whims rather than the sound exercise of his lawful authority,” said the lawsuit, filed by the states’ attorneys general in the U.S. Court of International Trade.

The states, including New York, Illinois and Oregon, are the latest parties to take the Trump administration to court over the tariffs. Their case comes after California filed its own lawsuit last week, in which Gov. Gavin Newsom and the state attorney general accused the administration of escalating a trade war that has caused “immediate and irreparable harm” to that state’s economy.

Officials and businesses from Oregon, the lead plaintiff in the suit filed Wednesday, have also expressed concerns about the vulnerability of the state’s trade-dependent economy, as well as its sportswear industry, as a result of the tariffs.

“When a president pushes an unlawful policy that drives up prices at the grocery store and spikes utility bills, we don’t have the luxury of standing by,” said Dan Rayfield, Oregon’s attorney general, in a statement. “These tariffs hit every corner of our lives — from the checkout line to the doctor’s office — and we have a responsibility to push back.”

Asked about the latest lawsuit, Kush Desai, a White House spokesman, called it a “witch hunt” by Democrats against Mr. Trump.

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

The other states in the suit are Arizona, Colorado, Connecticut, Delaware, Maine, Minnesota, Nevada, New Mexico and Vermont. All of the states have Democratic attorneys general, though Nevada and Vermont have Republican governors.

Mr. Trump’s tariffs have shocked and upended the global trade industry. He set a 145 percent tariff on goods from China, 25 percent on Canada, and 10 percent on almost all imports from most other countries.

The moves have drawn legal challenges from other entities as well, including two members of the Blackfeet Nation, who filed a federal lawsuit in Montana over the tariffs on Canada, saying they violated tribal treaty rights. Legal groups like the Liberty Justice Center and the New Civil Liberties Alliance have also sued.

“I’m happy that Oregon and the other states are joining us in this fight,” said Ilya Somin, a law professor at George Mason University, who is working on the Liberty Justice Center’s lawsuit.
