As Trump Discovers Gas Price Gouging, Democrats Offer a Solution: Tax Big Oil

"Mr. President: I have a windfall excess profits bill you could support," said one Democratic senator.

President Donald Trump said Tuesday that he has directed the US Department of Justice to investigate fossil fuel companies for not lowering gasoline prices as the cost of oil declines amid the prospect of an end to the Iran War.

"The big Oil Companies are not dropping their price at the pump commensurate with the sharply lower prices they are paying for Oil. Those prices are dropping like a rock! In other words, customers are being 'gouged,'" Trump said on his Truth Social network.

"I have instructed the DOJ to immediately start looking into this," he added. "Gasoline prices better start going down a lot faster than what I’m seeing!"

While benchmark West Texas Intermediate and Brent Crude oil prices have fallen to their lowest levels since Trump launched the illegal US-Israeli war of choice on Iran on February 28, the average price for a gallon of unleaded gasoline in the United States was $3.93 per gallon on Wednesday, around one-third higher than it was the day before the war started but down from a high of $4.52 a month ago, according to the American Automobile Association.

"The price of fuel is not only a national security issue, it impacts the wallet of every American," an unnamed Trump administration official told ABC News on Wednesday following the president's post. "We will always commit to ensuring affordability in this nation."

Responding to Trump's post, US Sen. Sheldon Whitehouse (D-RI) noted on social media that he has a solution for Big Oil price gouging.

In March, Whitehouse and Rep. Ro Khanna (D-Calif.) reintroduced the Big Oil Windfall Profits Tax Act “to curb profiteering by oil companies and provide Americans relief at the gas pump.”

The legislation—which only applies to large oil companies—would impose a per-barrel tax “equal to 50% of the difference between the current price per barrel of oil and the average price per barrel last year, when big oil companies were already earning large profits.”

Democrats in both chambers of Congress have also called for the prosecution of corporations that use the war as a pretext for price gouging.

Polling has shown that Americans largely support a tax on Big Oil windfall profits, which, according to The Guardian, amounted to $23 billion in the first month of the war alone—or $30 million per hour.

NEW: As Americans face rising oil costs, Maine Senate candidate Graham Platner has released an energy plan aiming to “End Big Oil Price Gouging.”We find voters support key elements of the plan, including an oil windfall tax to freeze or lower electricity rates.

Trump has been a staunch supporter of fossil fuel companies. While running for reelection on a "drill, baby, drill" energy platform, he reportedly promised Big Oil executives that he would eviscerate climate regulations enacted by the Biden administration if they gave $1 billion to his campaign.

Fossil fuel interests spent nearly $450 million during the 2024 election cycle on campaign contributions, lobbying, and efforts supporting Republican causes and candidates, including Trump.

As pump prices soared and Americans suffered amid Trump's war, the president—who promised gas under $2 a gallon and no new warssaid that “when oil prices go up, we make a lot of money."

Last week, the Institute on Taxation and Economic Policy estimated that Americans have paid nearly $54 billion extra for gas and fuel—more than $400 per household—than they would have if the war never happened.
