Leonard Leo

Leonard Leo is an American conservative legal activist who served as the longtime executive vice president of the Federalist Society and who has been the principal architect of the Supreme Court's conservative supermajority through his role advising President Donald Trump on the selection and confirmation of Neil Gorsuch (2017), Brett Kavanaugh (2018), and Amy Coney Barrett (2020). Leo became chairman of the Teneo Network in 2021 and has directed approximately one billion dollars in dark-money spending through a network of linked 501(c)(4) vehicles, including the Judicial Crisis Network (now the Concord Fund), to reshape the American judiciary and, through the Teneo chairmanship, to extend the operational model across American institutional life.¹²³

The Federalist Society and the Judicial-Selection Project

Leo's career at the Federalist Society began in the 1990s and he rose to executive vice president, the operational principal of the organization. The Federalist Society is the conservative legal-networking organization that functions as the pipeline for federal judicial nominations under Republican administrations, and Leo's role placed him at the center of the selection process for every conservative federal judge confirmed across the George W. Bush and Trump administrations. Leo assisted Clarence Thomas in his 1991 confirmation hearings and subsequently led the confirmation campaigns for John Roberts, Samuel Alito, Gorsuch, Kavanaugh, and Barrett.¹⁴

The ProPublica profile "We Don't Talk About Leonard" (March 2023) is the foundational investigative document on Leo's role. The profile documents how Leo advised Trump on all three Supreme Court nominations, how the Federalist Society's judicial-selection pipeline fed the nominations, and how the dark-money infrastructure funded the confirmation campaigns. Senator Sheldon Whitehouse (D-RI) has documented on the Senate floor and in Senate Judiciary Committee proceedings that Gorsuch and Kavanaugh were the "big prize" for Leo's dark-money donors, locking in a conservative majority that delivered subsequent wins for the Republican donor interests.²⁵

The Dark-Money Infrastructure

Leo's dark-money operation runs through a network of linked 501(c)(4) organizations that permit political spending without donor disclosure. The primary vehicle is the Judicial Crisis Network (now the Concord Fund), which Citizens for Responsibility and Ethics in Washington reported brought in nearly 48.1 million dollars in a single reporting period to support the conservative judicial-confirmations project. The broader network of Leo-linked organizations has funneled over one billion dollars in undisclosed spending across the judicial-selection, political-advocacy, and institutional-influence operations, per the Alliance for Justice and ProPublica investigations.²⁵⁶

The dark-money infrastructure operates through a layered structure of 501(c)(4) social-welfare organizations and 501(c)(3) charities that transfer funds to each other in chains designed to obscure the original donors. The Senate Judiciary Committee under Chairman Dick Durbin has sought Leo's records and testimony; Leo has declined to comply, and his counsel's letter to the Committee (July 2023) pushed back on the "dark money" and "phony front groups" characterizations. The investigative record relies on leaked tax filings, whistleblower disclosures, and the reporting of ProPublica, CREW, and the Alliance for Justice.³⁷

The Teneo Chairmanship and the Institutional Expansion

Leo became chairman of the Teneo Network in 2021, bringing the dark-money infrastructure he had built through the Federalist Society, the Judicial Crisis Network, and the broader conservative-judicial operation into a network whose stated goal (per the ProPublica investigation) is to "crush liberal dominance" across American law, finance, media, academia, and culture. The Teneo chairmanship extended the Leo operational model from the courts, where it had succeeded in producing the conservative supermajority, to the rest of American institutional life.⁸

The Leo-Thiel relationship runs through the shared dark-money infrastructure and the shared Teneo-network institutional terrain. The Thiel-tied Per Aspera Policy vehicle that steered funds to the Protect Ohio Values PAC for the JD Vance Senate campaign operates in the same 501(c)(4) dark-money ecosystem as the Leo-linked vehicles, and both networks operate through the Teneo Network for the broader institutional-placement function.⁸⁹

The Trump Schism

Trump publicly attacked Leo in 2025, calling him someone who "probably hates America." The CBS Evening News reported on the schism between the president whose judicial selections Leo had architected and the operative who had built the selection infrastructure. The attack followed documented tensions within the post-2024 Republican coalition over personnel choices and strategic direction, with Leo reported to be frustrated with the Trump administration's appointments outside the judicial pipeline.¹⁰

The schism did not affect the underlying judicial infrastructure. The Gorsuch, Kavanaugh, and Barrett confirmations are permanent, and the conservative supermajority on the Supreme Court is the structural outcome Leo's operation produced. The supermajority delivered the 2022 Dobbs decision overturning Roe v. Wade, the expansion of Second Amendment gun rights, the rollback of federal regulatory authority under the major questions doctrine, and the presidential-immunity ruling in Trump v. United States (2024).¹⁰

Leo's response to the Trump attack was measured. He did not publicly retract his support for the judicial-selection infrastructure, and his network continued to operate through the Teneo Network chairmanship and the Concord Fund / JCN dark-money operation. The schism is a documented internal-republican conflict between the electoral and institutional wings of the coalition, not a dismantling of the judicial infrastructure that both wings had built together.¹⁰
