US President Donald Trump said he ordered an investigation into major oil companies over high gasoline prices as the US leader faces criticism over the impact of the Mideast war, AFP reports.

“The big Oil Companies are not dropping their price at the pump commensurate with the sharply lower prices they are paying for Oil,” Trump wrote on Truth Social.

“Those prices are dropping like a rock! In other words, customers are being ‘gouged’,” he added.
