A coalition of government watchdog groups is calling on the U.S. Senate to launch an investigation into Justice Samuel Alito, alleging that his personal financial holdings in the energy sector create a direct conflict of interest. In a letter sent to the Senate Judiciary Committee, the groups argue that Alito’s failure to recuse himself from cases involving major oil companies undermines the impartiality of the Supreme Court.
The controversy centers on Samuel Alito oil stock conflicts and a perceived pattern of “irregular recusal” in cases that could financially benefit the energy industry. The coalition—which includes the League of Conservation Voters, the Center for Biological Diversity, the Revolving Door Project, and True North Research—asserts that Alito is the only justice on the high court with direct holdings in energy companies.
The urgency of the request follows the Supreme Court’s decision in February to hear a case brought by oil giants Suncor Energy and Exxon. The companies are seeking a ruling that federal law prevents state and local governments from filing lawsuits against oil and gas firms for the climate-warming effects of their products. While the court did not specify which justices supported the petition, the watchdog groups note that Alito did not recuse himself from the proceedings.
Financial Ties to the Energy Sector
According to the justice’s most recent financial disclosure, filed in August 2023 and covering the 2024 period, Alito holds individual stocks worth between $60,007 and $245,000 in ConocoPhillips, Phillips66, and five other energy firms. The letter highlights a holding of up to $100,000 in a Vanguard fund where Exxon is listed as the third-largest holding.
Lisa Graves, a former senior Justice Department official and current director of True North Research, argues that these financial stakes should be an automatic disqualifier. “No judge on any court, including the high court, should be allowed to hear cases where he or she have a financial stake in those cases,” Graves stated.
The conflict is particularly acute given the scale of the “climate deception” lawsuits currently moving through the legal system. More than 70 state and local governments have accused oil companies of misleading the public about their role in the climate crisis. Because a ruling in favor of Suncor or Exxon could set a precedent affecting the entire industry, advocates argue that any holding in an oil company constitutes a conflict.
The Paul Singer Connection
Beyond direct stock ownership, the watchdog groups point to Alito’s relationship with Republican billionaire donor Paul Singer as another area of concern. Singer, who manages the hedge fund Elliott Investment Management, holds more than 52 million shares of Suncor, valued at over $2.3 billion.

This relationship has been under scrutiny since June 2023, when ProPublica reported that Alito failed to disclose a private jet flight to Alaska for a 2008 fishing trip funded by Singer. In a response published in the Wall Street Journal, Alito defended the trip, stating that ethics rules at the time did not require the disclosure and that he had no duty to recuse himself from cases involving Singer.
However, the coalition’s letter suggests that Alito’s recent decision to participate in the Suncor petition represents an “indefensible breach of ethical boundaries,” arguing that a victory for the oil majors would benefit both Alito’s personal portfolio and his associate’s massive investments.
A ‘Toothless’ Ethics Framework
The dispute highlights a growing tension over the Supreme Court’s internal governance. In 2023, the court adopted its first formal ethics code following a series of scandals involving several justices. The code advises that justices should recuse themselves if their “impartiality might reasonably be questioned,” but it leaves the final decision to the individual justices themselves.
Legal experts and watchdog groups have criticized the code for lacking an enforcement mechanism. Unlike the standards applied to lower federal judges, the Supreme Court’s guidelines allow justices to remain on a case if their vote is deemed necessary to resolve the matter.

| Ethics Measure | Function | Primary Criticism |
|---|---|---|
| 2023 Ethics Code | Guidance on impartiality and recusal | No independent enforcement mechanism |
| Conflict Software | Scans filings for stock-ticker conflicts | Relies on voluntary party disclosure |
| Financial Disclosures | Annual reporting of assets and income | Significant time lag in public reporting |
To address these concerns, the court recently introduced software designed to scan filings for potential conflicts by requiring parties to list stock-ticker symbols. Despite this, Hannah Story Brown, deputy research director at the Revolving Door Project, argues that software is insufficient for industry-wide impacts. She maintains that a “blanket refusal” to hear such cases is the only ethical path for Alito.

The next critical window for transparency will occur next year, when justices are required to report their 2026 holdings. However, as Lisa Graves noted, the court may have already issued a ruling on the Suncor case before those disclosures become public. The Senate Judiciary Committee has not yet announced whether it will act on the coalition’s request for an investigation.
