Sen. Sheldon Whitehouse rallied 89 Democratic lawmakers behind a Supreme Court brief demanding financial transparency from the other side of a major climate lawsuit, while quietly omitting that the law firm driving the case has funneled thousands of dollars into his own campaigns.

Whitehouse, a Rhode Island Democrat, filed the amicus brief in support of a climate lawsuit brought by the city and county of Boulder, Colorado, against oil companies. The case, docketed as No. 25-170, is scheduled for oral argument on October 5. The brief includes a chart alleging that briefs filed in support of the oil-company defendants were bankrolled by "fossil fuel-linked donors" such as Koch Brothers, Chevron, and ExxonMobil. But the brief says nothing about Whitehouse's own financial ties to the plaintiffs' side, specifically, to the founding partners of Sher Edling, the law firm spearheading the climate litigation campaign against the oil industry.

Victor Sher and Matt Edling, Sher Edling's founding partners, have donated thousands of dollars to Whitehouse's election campaigns, public records on OpenSecrets show. Both men also filed their own separate amicus brief in the same Boulder case, alongside Michael Burger, an attorney who serves as "of counsel" with Sher Edling and as executive director of the Sabin Center for Climate Change Law at Columbia University.

Whitehouse has long positioned himself as a crusader for disclosure in Supreme Court filings. He has publicly advocated for amicus brief financial transparency, demanding that outside parties reveal who funds their briefs. Yet when it comes to his own donor relationships with the very firm prosecuting the case he is supporting, the senator's standard apparently does not apply to himself.

The Wall Street Journal's editorial board flagged this contradiction as far back as 2019, calling out Whitehouse for pushing amicus disclosure rules while failing to reveal Sher's and Edling's donations in briefs he filed supporting cases their firm litigated. Seven years later, the pattern has not changed.

Boulder's 2018 lawsuit aims to make oil companies pay for bad weather

Boulder filed its lawsuit in 2018, claiming oil companies concealed the impact of their products on the climate and should be held liable for damages caused by severe weather. The case is one of dozens of similar climate lawsuits winding through state courts across the country, all following a similar playbook: use tort liability to extract money from energy producers and, in effect, set national energy policy through courtrooms rather than through Congress.

One of the lawyers who worked for years on Boulder's legal team laid out the strategy in plain terms. David Bookbinder, now director of law and policy at the Environmental Integrity Project, spoke at a Federalist Society webinar in September 2025 titled "Can State Courts Set Global Climate Policy." His explanation of the lawsuit's purpose left little room for ambiguity.

"Essentially, the tort liability is an indirect carbon tax. You sue an oil company, an oil company is liable. The oil company then passes that liability on to the people who are buying its products. In some sense, it is the most efficient way, the people who buy those products are now going to be paying for the cost imposed by those products."

Read that again. The people who buy gasoline, heating oil, and natural gas would foot the bill. Bookbinder did not describe a remedy for injured plaintiffs. He described a backdoor tax on energy consumers, imposed not by elected legislators but by state-court judges. That is the goal Whitehouse and 89 of his colleagues are asking the Supreme Court to protect.

Democrats have shown a willingness to use courts as a policy lever on multiple fronts. Recent clashes over Supreme Court rulings have exposed a pattern: when the legislative process does not deliver the outcome progressives want, they turn to litigation and judicial pressure instead.

Jordan's letter exposes a deeper web of influence on judges

The undisclosed donations are only one layer of the problem. Rep. Jim Jordan, the Ohio Republican who chairs the House Judiciary Committee, sent a letter to Victor Sher on April 28, 2026, seeking information about Sher Edling's involvement in the Environmental Law Institute's Climate Judiciary Project. That project produces training materials for judges overseeing climate cases, materials that, according to Jordan's letter, are not as neutral as they appear.

Jordan's letter states that "evidence exists that Mr. Burger may have ghostwritten parts of a chapter on Climate Science in the Fourth Edition of the Federal Judicial Center's Reference Manual on Scientific Evidence." The Federal Judicial Center publishes the manual as a resource for federal judges handling complex scientific questions. If Burger, a lawyer whose firm represents plaintiffs in climate lawsuits, shaped the scientific guidance judges rely on, the conflict of interest would be severe.

Jordan's letter also flagged that Burger's research appeared in the Climate Judiciary Project's materials without any disclosure of his financial interest in the plaintiffs' position. The concern is straightforward: a litigation activist helped write the playbook that judges use to evaluate the very claims his clients are making.

The Federal Judicial Center apparently agreed the situation warranted action. After twenty-seven state attorneys general objected that the chapter was authored by biased climate litigation activists and designed to predispose judges in favor of plaintiffs, the FJC removed it from the manual entirely.

That removal is significant. The FJC does not pull chapters from its reference manuals lightly. When more than half the states' top law enforcement officers raise alarms about planted bias in a judicial training document, and the agency responds by scrubbing the material, it validates the concern that the climate litigation network has been working to tilt the playing field from the inside.

The Supreme Court has been a focal point for Democratic frustration on multiple fronts this term. Recent rulings that went against progressive priorities have intensified the left's efforts to influence outcomes through every available channel, including, it now appears, the scientific materials judges consult before hearing climate cases.

Whitehouse demands transparency he refuses to practice

The senator's brief in the Boulder case dedicates space to a chart mapping the financial backers of the opposing side's amicus filings. The implication is clear: Whitehouse wants the justices to view the defendants' supporters as compromised by industry money. Koch Brothers, Chevron, and ExxonMobil are named explicitly, presented as evidence that the defense-side briefs should be viewed with suspicion.

But Whitehouse applied no such scrutiny to his own side. He did not disclose that the founding partners of the firm leading the plaintiffs' case had donated to his campaigns. He did not flag that one of the lawyers on his side's separate amicus brief is accused of ghostwriting judicial training materials. He asked the Court to follow the money, but only the other side's money.

This is not a new accusation. The Wall Street Journal raised the same point in 2019. Whitehouse has had seven years to address the contradiction, and the fact that he filed another brief in 2026 with the same omission suggests he has no intention of doing so.

When Democrats have faced unfavorable court outcomes, their responses have ranged from procedural maneuvers to outright institutional pressure. Whitehouse's approach fits the pattern: use the courts to advance policy goals that cannot survive a legislative vote, and insulate that strategy from the same transparency standards applied to opponents.

Dozens of amicus briefs landed in the Boulder case from both sides. The Supreme Court will hear oral argument on October 5 in a case that could determine whether state courts can effectively impose a national carbon tax through tort liability, a policy Congress has never passed. The Court's docket this term is already packed with cases that carry enormous policy consequences.

If the plaintiffs prevail, the costs will not come out of oil company profits. Bookbinder said so himself. They will land on the consumers who heat their homes, fill their tanks, and power their businesses. That is not a legal remedy. It is a policy choice, one that no voter was ever asked to approve.

Whitehouse wants the Supreme Court to police the funding behind his opponents' briefs. He could start by disclosing his own.
