(Salem, OR) -- Governor Tina Kotek is joining 18 other Governors in signing a letter urging Congress to take back its authority on tariffs. The U.S. Supreme Court overturned most of President Trump's initial attempt to impose tariffs. Now, he's attempting to use another law impose 15 percent global tariffs. Oregon has joined a coalition of states in a lawsuit against those tariffs. Kotek says Oregon's economy relies heavily on international trade and the tariffs will drive up prices.
