US diesel hits record $6.27/gal; Trump energy promises under pressure ahead of midterms

US average diesel price reached a record $6.27 per gallon, according to AAA, contradicting President Trump's repeated promises to lower pump prices. The surge comes as Trump claims Ukraine and Russia agreed to halt attacks on energy infrastructure, a day after he criticized Kyiv for strikes on Russian refineries. The development underscores energy-market fragility and political stakes ahead of November midterms.
