The Justice Department's Antitrust Division and the Federal Trade Commission fired off a joint letter to state attorneys general on Friday, urging them to open investigations into oil companies suspected of manipulating gasoline prices or colluding with competitors. The three-page letter, first reported by the Washington Examiner, came nine days after President Donald Trump publicly directed the DOJ to look into whether major producers were gouging consumers at the pump.
The move marks a concrete federal escalation on an issue that hits every American driver. National average gas prices currently sit at roughly $3.82 per gallon, AAA data shows, down from about $4.26 last month but still well above the $3.16 average at this time last year.
That gap between falling crude oil costs and stubbornly high retail prices is exactly what prompted Trump's June 24 Truth Social post, which the agencies placed prominently at the top of their letter to state officials.
Trump did not hold back when he laid out the problem on Truth Social:
"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.' I have instructed the DOJ to immediately start looking into this."
Nine days later, the DOJ and FTC answered with the joint letter. Associate Attorney General Stanley Woodward framed the effort in plain economic terms:
"Affordable energy is essential to a thriving American economy. The Antitrust Division is committed to working alongside state law enforcement partners to provide resources and support to protect consumers from anticompetitive behavior that raises the price of gas. The Antitrust Division will use all available tools to ensure that companies are held accountable for unlawfully manipulating the market."
The letter warned that volatility in oil markets "does not suspend either the antitrust laws or state consumer protection laws." Businesses, the agencies wrote, may not use changing market conditions "as cover for anticompetitive practices, fraud, or any other lawlessness that harms Americans."
That language leaves little room for ambiguity. The federal government is telling state-level enforcers to treat price manipulation the way they would any other consumer fraud, and offering federal muscle to back them up.
The core question is straightforward: if crude oil prices have dropped sharply, why haven't pump prices followed? Newsmax reported that the U.S.-Iran war shut the Strait of Hormuz for more than three and a half months, disrupting roughly one-fifth of the world's oil supply and sending prices skyward. Now that crude has retreated from those wartime highs, the national average remains 84 cents above last year's level.
Chevron CFO Eimear Bonner acknowledged the disconnect but pointed to market mechanics, telling reporters, "It's going to take time though", a reference to the lag between falling crude prices and retail relief. That explanation may satisfy some analysts. It does not satisfy millions of Americans who watch crude prices fall on the news and then pay the same amount or more the next morning at the gas station.
The administration's posture is that market lag is one thing; coordinated price manipulation is another. And the DOJ intends to find out which one is happening.
The joint letter pledged both civil and criminal enforcement tools against companies found violating antitrust laws. It directed consumers to report suspected violations through the DOJ's Citizen Complaint Center and the FTC's fraud reporting portal.
Perhaps most notable is the spotlight the letter placed on the Antitrust Division's whistleblower rewards program, which pays informants between 15 and 30 percent of criminal fines collected in qualifying cases. That is not a symbolic gesture. Earlier this year, the DOJ awarded its first $1 million whistleblower payment to an individual who helped uncover an online used-car price-fixing conspiracy.
The message to industry insiders is clear: if you know about collusion, there is real money on the table for coming forward.
States with price-gouging statutes were specifically encouraged to determine whether enforcement actions are warranted under those laws. The letter effectively deputizes state attorneys general as front-line investigators while the federal agencies monitor petroleum markets from above.
The gasoline pricing push does not exist in a vacuum. Earlier the same week, the DOJ filed a federal lawsuit against Cal-Maine Foods, Hickman's Egg Ranch, Versova Holdings, and others, alleging a conspiracy to manipulate industry price benchmarks and inflate wholesale egg prices through coordinated bidding strategies and private trades. That suit seeks to bar future anticompetitive conduct and enforce proposed settlements requiring compliance programs and restrictions on communications with competitors.
The egg case and the gasoline letter share a common thread: the Trump DOJ is signaling that price manipulation, whether in the grocery aisle or at the pump, will draw federal scrutiny and real consequences.
That posture extends well beyond consumer pricing. The DOJ has been active on multiple fronts, including opening a federal probe into Sen. Ruben Gallego over alleged campaign finance violations and pursuing other high-profile enforcement actions.
Just The News reported that the joint letter warned companies and individuals who "seek to unlawfully exploit our nation's citizens will face federal investigation, civil liability, and criminal prosecution." That triple threat, investigation, civil suits, and criminal charges, is not language agencies use casually.
For all the forceful language, several questions remain open. No specific oil companies have been publicly named as targets of any pending investigation. No state attorney general has yet announced plans to open a probe in response to the letter. And the letter itself, while aggressive in tone, is a directive to investigate, not a completed enforcement action.
The DOJ's broader enforcement agenda has shown a willingness to follow through. A grand jury targeting a China-based billionaire over alleged funding of U.S. leftist groups and a historic push to file 250 denaturalization cases by the end of the fiscal year suggest an agency that is not simply issuing press releases and moving on.
Whether the gasoline pricing effort produces indictments, settlements, or simply market-correcting pressure remains to be seen. But the combination of federal monitoring, state-level investigation authority, whistleblower incentives, and the explicit threat of criminal prosecution creates a framework that goes far beyond rhetorical saber-rattling.
The administration has also demonstrated it will use the DOJ across a range of enforcement priorities, from charging an illegal immigrant with voting in a federal election to confronting corporate price manipulation. The common denominator is accountability, the idea that laws on the books should be enforced, not treated as suggestions.
Americans filling up their tanks this holiday weekend are paying 84 cents more per gallon than they did a year ago, even as crude oil prices have retreated from their wartime peaks. The oil industry's explanation, that price adjustments take time, may be true in part. But "it takes time" is not a legal defense against collusion, and it is not an answer that satisfies families watching their fuel budgets climb while industry profits hold steady.
The DOJ and FTC have now put the industry on formal notice. State attorneys general have been handed federal resources and encouragement. Whistleblowers have been offered a cut of the fines. The infrastructure for accountability is in place.
If oil companies are playing it straight, they have nothing to worry about. If they are not, the federal government just made it a lot harder to hide.
