Trump backs diesel export ban as fuel prices hit record highs

President Donald Trump endorsed a diesel export ban on Tuesday to combat record-high fuel prices, aligning with farm-state lawmakers who say costs are hurting farmers, as wars in Iran and Ukraine disrupt global supply. The proposal faces opposition from Trump's own energy officials, including Energy Secretary Chris Wright, who warn it could reduce refinery output and gasoline supply, while Interior Secretary Doug Burgum cited risks of retaliatory measures from energy-exporting countries. A ban would likely lower Gulf Coast prices temporarily but tighten supplies in Europe, which relies heavily on U.S. diesel exports, potentially damaging key allies. Trump also discussed Ukrainian refinery attacks with President Zelensky.
