A deep-pocketed nonprofit group based by the conservative activist Leonard A. Leo gave away $182.7 million in a yr’s time, a brand new tax submitting reveals, demonstrating how aggressively it has labored behind the scenes to prop up different teams and causes on the proper.

The group, Marble Freedom Trust, was shaped in 2020 and was funded by a present of greater than $1.6 billion — a unprecedented windfall that resulted from a single donor’s contribution of 100% of an organization’s shares earlier than the corporate was bought, leaving Marble with the proceeds of the sale, The New York Times reported last year.

Mr. Leo, a lawyer and former government on the Federalist Society, has been instrumental in conservatives’ yearslong effort to push the federal judiciary to the proper, each by his direct steerage to Republican leaders and by financing conservative causes. In latest years, he has built an opaque, far-reaching network of organizations — lots of which have funding sources that aren’t required to be disclosed — that may affect elections and different issues, together with training coverage, abortion and campus free speech points.

In a press release responding to questions on Marble’s work, Mr. Leo described it as an try and match Democratic efforts on the planet of so-called darkish cash, a time period used to explain the huge move of funds — usually from untraceable donors — by nonprofits and different organizations into politics and political causes. Democrats raised and spent more dark money for the 2020 election than Republicans did.

“It’s high time for the conservative movement to be among the ranks of George Soros, Hansjörg Wyss, Arabella Advisors and other left-wing philanthropists, going toe-to-toe in the fight to defend our Constitution and its ideals,” Mr. Leo mentioned.

(Mr. Wyss, a Swiss billionaire, is a major donor to left-leaning nonprofit groups; Arabella Advisors is a for-profit consulting group that administers a network of progressive nonprofit organizations that collectively spent practically $1.2 billion in 2020.)

Marble Freedom Trust, a tax-exempt 501(c)(4) “social welfare” group, is a centerpiece of Mr. Leo’s community. The group’s said mission is to “maintain and expand human freedom consistent with the values and ideals set forth in the Declaration of Independence and the Constitution.”

It was not instantly clear from the group’s file of contributions how Marble was realizing that mission. The latest submitting for Marble — a tax file for the yr ending on April 30, 2022, that was obtained by the liberal transparency group Accountable.US — doesn’t reveal a lot in regards to the final vacation spot of the $182.7 million.

In the yr ending final April, based on the submitting, Marble gave $153.8 million to the Schwab Charitable Fund, a supervisor of donor-advised funds, which permit individuals and entities to direct their deposits over time into charitable organizations, together with some politically inclined teams and establishments.

Another $28.9 million went to the Concord Fund, a conservative advocacy group. Formerly often known as the Judicial Crisis Network, the group has acted as a funding hub up to now, giving tens of tens of millions of {dollars} in grants to allied nonprofit teams and supporting in-house tasks, together with opposition to Democrats’ makes an attempt to increase voting entry.

From these two organizations, it’s inconceivable to straight hint the place the Marble cash went.

During that approximate time interval, based on Schwab’s tax filings, Schwab gave $141.5 million to a different group linked to Mr. Leo, the 85 Fund — a nonprofit group that claims its mission is “to educate the public and support activities that highlight the relationship between structural limits on government power and the protection of our dignity and our freedom.”

The 85 Fund backs the Honest Elections Project, a conservative group based in 2020 that has labored in states throughout the nation to restrict voting access.

Some of the cash that flows by Mr. Leo’s community of nonprofit teams goes to for-profit firms he controls. In 2021, the 85 Fund paid $21.75 million to CRC Advisors, a consulting agency run by Mr. Leo, based on the 85 Fund’s tax filings.

Several different entities in Mr. Leo’s community, together with the Concord Fund, have additionally paid CRC Advisors tens of millions of {dollars} within the final two years, tax data present.

“Marble Freedom Trust is Leonard Leo’s billion-dollar slush fund to erode democracy,” mentioned Kyle Herrig, the president of Accountable.US. “With all this money under his control, Leo can push his extreme agenda by influencing conservative lawmakers on Capitol Hill, deploying state attorneys general to do his bidding and moving extreme bills in state legislatures.”

In a press release, Mr. Leo mentioned that CRC Advisors “employs nearly 100 best-in-class professionals whose expertise goes across all aspects of public affairs, and we deliver results that are leading the conservative movement to win more than it has ever before.”

Marble’s grants final yr declined barely from the earlier yr, when the group reported practically $229 million in grants, together with to Concord and the 85 Fund.

Since the $1.6 billion windfall — which got here from Barre Seid, an electronics manufacturing mogul — Marble has obtained no contributions or grants, however it did report $26.6 million in funding revenue final yr. As of a couple of yr in the past, Marble nonetheless had $1.2 billion to spend.

Marble’s tax submitting additionally reveals that Mr. Leo’s wage for his part-time function on the firm elevated to $400,000 from $350,000.

Mr. Leo’s work, and his longtime relationship with Justice Clarence Thomas, have come below new scrutiny lately. The Washington Post reported last week that Mr. Leo had organized for Justice Thomas’s spouse, the conservative activist Ginni Thomas, to be paid tens of hundreds of {dollars} for consulting work, and had urged to maintain her identify off the paperwork.

In a press release, Mr. Leo mentioned the fee didn’t current a battle of curiosity with the court docket. “It is no secret that Ginni Thomas has a long history of working on issues within the conservative movement,” he mentioned. “The work she did here did not involve anything connected with either the court’s business or with other legal issues.”
