President Donald Trump said Sunday that he is considering a ban on U.S. diesel fuel exports, saying the administration could take the step as it looks for ways to address high diesel prices.

“We’re looking at it very seriously. We may do it,” Trump told a Fox News reporter while attending the Presidents Cup golf tournament final near Chicago. He acknowledged that restricting diesel exports could also affect gasoline prices.

The proposal comes as diesel prices have risen sharply, creating pressure on the administration to find ways to lower fuel costs for American consumers and businesses. Diesel is particularly important to the agricultural and transportation industries, where fuel costs can directly affect operating expenses.

Several farm-state lawmakers have urged Trump to restrict diesel exports during the fall harvest season, arguing that keeping more fuel in the United States could help increase domestic supplies and reduce prices.

The proposal has also exposed differences within the administration over how to address the diesel market. Energy Secretary Chris Wright has argued against an export ban, saying such a restriction could make the fuel market more difficult rather than lowering prices.

Trump has continued to leave the option open as his administration considers other measures to address energy costs. The president said earlier that he expected to make a decision on whether to restrict diesel exports quickly.

A diesel export ban would represent a significant intervention in the U.S. fuel market, potentially redirecting supplies that American refiners currently sell to foreign buyers toward the domestic market. The administration has not announced a final decision or a timeline for implementing such a policy.
