Leonard Leo directs funding to the Concord Fund (formerly the Judicial Crisis Network), a 501(c)(4) nonprofit organization that has played a central role in advocating for conservative judicial nominations, shaping public opinion around Leo's initiatives, and supporting conservative policy advocacy and political campaigns. The Concord Fund, part of Leo's broader influence network, has received millions in donations, including anonymous donations and contributions from Leo-affiliated entities such as the Marble Freedom Trust, which Leo has helped allocate to advance his conservative agenda. Leaked documents reveal that Leo has used the Concord Fund as a front organization to channel 'dark money' from billionaire donors into conservative legal and judicial initiatives, specifically directing these funds to support campaigns for conservative judicial appointments, including those of Supreme Court justices. The organization's rebranding from the Judicial Crisis Network was intended to obscure its ties to Leo's network.

The Concord Fund was rebranded from the Judicial Crisis Network in 2020, a group closely associated with Leonard Leo. Leonard Leo played a key role in this rebranding, which was part of a broader strategy to distance the organization from its controversial past and obscure its ties to Leo's network while continuing its mission of influencing judicial appointments, funding conservative judicial and policy campaigns, and advocating for conservative policy.
