Trump summons refiners to White House as diesel price spike tests voters

Diesel prices in the US surged toward new highs after President Trump summoned major refiners to the White House to press for steps to curb inflation by expanding refining capacity amid Iran-related supply disruptions. Wholesale diesel jumped about 7% to $4.71 a gallon in New York Harbor, signaling higher consumer costs ahead of elections. Analysts say refiners are already operating at or near capacity, so prices could push toward a 2022-record if disruptions persist, while officials and industry executives discussed ways to boost capacity and energy production. Trump touted energy policies on Truth Social, but experts caution the administration has limited leverage over prices in a tight market.
