Oregon Attorney General Dan Rayfield is suing President Donald Trump over the administration鈥檚 aggressive tariffs that have routed markets and upended global trade.
, filed Wednesday in the U.S. Court of International Trade in New York, is the first time Oregon has led a coalition of states suing the second Trump administration.
The lawsuit argues the U.S. Constitution grants Congress, and not the President, the power to impose and collect taxes.
鈥淵et over the last three months, the President has imposed, modified, escalated, and suspended tariffs by executive order, memoranda, social media post, and agency decree,鈥 the lawsuit states. 鈥淭hese edicts reflect a national trade policy that now hinges on the President鈥檚 whims rather than the sound exercise of his lawful authority.鈥
Oregon is highly trade-dependent and vulnerable to tariffs. Last year, companies in the state imported more than $28 billion in parts and finished products, and exported over $34 billion.
Economists have and deal a blow to the state鈥檚 manufacturing sector 鈥 similar to how import taxes affected the state during the first Trump administration.
This month, Trump declared a national emergency over the United States鈥 trade deficit and rolled out sweeping tariffs that tanked global markets and sowed more uncertainty for businesses large and small, along with industries such as automobiles. On April 9, the White House paused reciprocal tariffs from taking effect for 90 days, though a new 10% across-the-board tariff did go into effect along with new tariffs against China amounting to 145%.
Officials with U.S. Customs and Border Protection, the agency responsible for collecting tariffs, did not immediately respond to a request for comment.
Earlier this week, Trump said tariffs against China would likely decrease.
鈥145% is very high and it won鈥檛 be that high,鈥 the president . 鈥淚t won鈥檛 be anywhere near that high. It鈥檒l come down substantially. But it won鈥檛 be zero.鈥

According to Oregon鈥檚 lawsuit, the national emergency the president declares must come from 鈥渦nusual and extraordinary threats鈥 from outside the U.S. in order to tap the powers granted under the International Emergency Economic Powers Act.
鈥淏y 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,鈥 the lawsuit states. 鈥淭he President has no authority to arbitrarily impose tariffs as he has done here.鈥
The lawsuit also notes the Act does not specifically name tariffs, and no president has used the law like this since its passage.
At an event Monday, a Sen. Ron Wyden (D-Oregon) that tariffs could result in rising prices and potential staff cuts.
Top among are computer chips and the components to help design and build them. The semiconductor industry employs more than 30,000 Oregonians, and some of the world鈥檚 biggest computer chip firms have a significant presence in the state.
Oregon treasurer Elizabeth Steiner, a Democrat, told OPB that tariffs mean businesses 鈥 especially small and medium size companies 鈥 are paying more for supplies while losing ground in global markets.
鈥淭hat鈥檚 a big deal,鈥 Steiner said during an interview Wednesday. 鈥淎nd that鈥檚 because of indiscriminate tariffs, imposed in ways that make absolutely no sense economically and do nothing to address trade imbalances, are completely poorly thought out, and have already played a significant adverse role in the world economy, let alone Oregon or the United States. So Oregon has every reason to speak up and to become part of legal action.鈥

Since Trump took office, Oregon has joined over a dozen multistate lawsuits against the administration鈥檚 actions. In this latest case, Oregon was joined by 11 other states, including Arizona, New York, Colorado and Minnesota, in the lawsuit filed Wednesday.
Last week, California became the and argued the president lacks the legal authority to act on his own.
鈥淧resident Trump has chosen to wield IEEPA to impose tariffs on the world at his whim, muddled by threats, additions, exceptions, exemptions, and pauses,鈥 the lawsuit Oregon filed Wednesday states. 鈥淭he direct consequence has been an erratic financial market and a destabilized U.S. and global economy.鈥
