U.S. President Donald Trump says he has instructed the Department of Justice to open an investigation into whether major oil companies are “gouging” consumers through gasoline prices that are not falling as quickly as crude costs. In recent remarks and posts, Trump argues pump prices have not declined fast enough even as global oil prices drop, and he calls for action to address the gap. Multiple outlets report that Trump frames the issue as part of broader economic strain related to the Iran conflict, pointing to a recent interim or first-stage peace deal with Iran as contributing to lower crude prices. NBC News and other outlets describe Trump’s directive as immediate, while Fortune and the Daily Mail cite Trump’s repeated claim that gasoline prices “better start going down” faster than what he is seeing. The reports consistently state that Trump directs DOJ involvement rather than another agency and that the basis for the probe is the alleged lack of corresponding price reductions at the pump. The outlets do not provide details on specific companies, legal grounds, or expected timelines for the investigation.
