At least one Republican senator, Sen. Chuck Grassley (Iowa), has criticized the Trump administration's decision to temporarily remove some restrictions on Russian oil amid a gasoline price hike due to the conflict in Iran. Grassley argues that the money from selling Russian oil fuels the ongoing conflict in Ukraine and prolongs the war. He also criticizes the move, suggesting that it financially propels Russia's invasion of Ukraine. The move is part of a larger effort by the administration to reduce soaring oil and gas prices.
