President Donald Trump announced he has ordered an investigation into major energy companies, saying gasoline prices should be lower after wholesale oil costs fell on global markets. Brent crude rose to almost $120 a barrel in May after Iran closed the Strait of Hormuz, then fell to about $74 a barrel as diplomatic talks progressed. The U.S. average regular gasoline price fell to $3.93 a gallon, down from more than $4 in April. Speaking to reporters in the White House on Wednesday, Trump said the pump price should be about $2.25 a gallon and named Chevron, ExxonMobil, Shell and BP as examples. He instructed the Department of Justice to begin an immediate review. The American Petroleum Institute said fuel prices do not move in lockstep with crude oil and that the industry is working to restore stability. A DOJ spokesperson said the department is reviewing the request but has not confirmed the launch of an investigation. White House officials said Trump's remarks reflect a focus on short‑term market disruptions and that prices are expected to decline if the Iran situation is resolved. API spokesperson Bethany Williams said the sector shares the goal of affordable fuel and highlighted ongoing supply constraints. The investigation remains pending, and gasoline prices are still above pre‑war levels despite the recent decline.
