Sen. Elizabeth Warren (D-Mass) took to X on Sunday to deliver a blistering critique of President Donald Trump, arguing that Americans are getting gouged at the gas pump thanks to the ongoing war with Iran. Her claim: the conflict is costing U.S. drivers an extra $800 million every single day.

“Guess who’s getting richer?” Warren asked, before pointing a finger at oil company executives. She cited a Wall Street Journal investigation from early April that tracked the stock sales of top energy CEOs since the war started. According to that report, Chevron Corp. (Chevron (CVX)) CEO Mike Wirth has made over $104 million, ConocoPhillips (ConocoPhillips (COP)) CEO Ryan Lance gained more than $54 million, and Baker Hughes Co. (Baker Hughes (BKR)) CEO Lorenzo Simonelli netted $33 million in stock trading. In total, energy executives have sold $1.4 billion worth of stock since the conflict began.

“The same Big Oil executives Trump promised to deliver for on day one,” Warren said in her post.

The senator’s comments come as gas prices remain elevated, with some states like California seeing prices above $6 per gallon. Other Democrats have also piled on. Sen. Catherine Cortez Masto (D-NV) criticized Trump’s “war of choice” in Iran, saying it’s straining fuel prices and hurting sectors like aviation.

Meanwhile, Trump himself has signaled that a diplomatic resolution with Iran isn’t imminent. In a recent interview, he cautioned against rushing into any agreement and hinted at possible military action if talks fail. The U.S. conducted strikes on Iranian missile sites and boats last week, and Iran’s Islamic Revolutionary Guard Corps claimed it downed a U.S. drone and fended off an F-35 fighter jet.

Warren’s math on the $800 million daily cost hasn’t been independently verified, but the broader point—that oil executives are cashing in while consumers feel the pinch—is resonating with voters as the 2026 midterms approach.
