Trump Asked for $1 Billion to Do Big Oil's Dirty Work. Meet the Billionaire Making It Happen

"Not familiar with Harold Hamm? You should be."

That's according to Washington Post climate policy editor Stuart Leavenworth, who shared the newspaper's Tuesday reporting on the fossil fuel executive's relationship with former President Donald Trump, the Republican nominee for the November election.

"This oil tycoon is bringing in millions for Trump," the editor noted, "and is relaying to Trump what the fossil fuel industry wants."

The Post's Josh Dawsey and Maxine Joselow revealed in May that during an event in Florida, Trump vowed to gut the Biden administration's climate regulations if elected in November as long as the oil and gas industry put $1 billion toward his campaign—a revelation that sparked alarm and even congressional investigations.

In Tuesday reporting described by other journalists as " great" and "important," the pair exposed how "Hamm, the billionaire founder of Continental Resources, called other oil executives and encouraged them to attend fundraisers and open their wallets" after the April dinner at Mar-a-Lago, Trump's Florida residence.

Hamm reportedly described the November contest as "the most important election in our lifetime" and "railed against President Joe Biden's energy policies." Following a disastrous debate performance against Trump, the Democratic incumbent passed the torch to Vice President Kamala Harris, who has since secured her party's nomination.

Donna Brazille, a political strategist and former Democratic National Committee chair, used the new reporting to compare the candidates. As she put it, "This oil tycoon brings in millions for Trump, and may set his agenda."

Hamm's top priorities, according to the Post, are "opening up more federal lands to drilling, easing the Endangered Species Act, and curbing numerous regulations at the Environmental Protection Agency."

Brazille pointed out that "meanwhile, as attorney general in California, Harris prosecuted oil companies for leaks from pipelines and storage tanks, and even sued the Obama administration."

Harris has quickly garnered support from various organizations concerned about the fossil fuel-driven climate emergency, including some that had declined to endorse Biden. Her running mate is Minnesota Gov. Tim Walz—a choice widely welcomed by green groups, despite his record on the Line 3 oil pipeline—while Trump picked Big Oil-backed Sen. JD Vance (R-Ohio).

Both Trump and Vance have made clear that if they win, they plan to "drill, baby, drill," a promise that wealthy figures in the fossil fuel industry seem to be buying. The Post reported that thanks in part to introductions by Hamm, "Trump has now 'called almost everyone in the sector,"" and "the money has been flowing in," with the industry contributing over $20.3 million.

Harris campaign spokesperson Joseph Costello said in a statement that "oil barons are bankrolling the Trump campaign because Donald Trump promises to impose their policy 'wish list' that will make them even richer at the expense of the middle class and a healthy future for our children."

"Trump's extreme Project 2025 agenda will give handouts to billionaires, crush jobs, and send costs skyrocketing," Costello added. "America is more energy independent than ever under the Biden-Harris administration, and Vice President Harris is helping create hundreds of thousands of good paying energy and manufacturing jobs—a boom for working families that Trump would dismantle."

Hamm—who initially backed two Trump primary challengers: Florida Gov. Ron DeSantis and former South Carolina Gov. Nikki Haley—did not respond to the Post's requests for comment while the campaign said that Trump "is proud to be supported by people who share his vision of American energy dominance to protect our national security and bring down the cost of living for all Americans."

More Perfect Union noted in response to the Tuesday reporting that Hamm is among dozens of billionaires backing Trump—who is also expected to push tax cuts for rich individuals and corporations if he returns to the White House.

As Sludgedetailed last month, ultrawealthy contributors to the Trump campaign and related groups include casino mogul Miriam Adelson, bankers Andy Beal and Warren Stephens, GOP donors Scott Bessent and Stephen Schwarzman, real estate investor Richard Kurtz, Jimmy John's founder James J. Liautaud, and crypto industry twins Cameron and Tyler Winklevoss.

They are joined by associates of billionaire Elon Musk—who created a pro-Trump super political action committee—and others in the tech industry, including Palmer Luckey, Tom Siebel, and Kenny Trout, as well as "New York City retail and oil refinery owner John Catsimatidis, an old friend of Trump's who has been a public defender of the former president's character and public record."
