The Solidarity Center has received over $86 million from the federal government since 2008; $61 million of that was given under President Biden. Three Solidarity employees joined Biden’s Labor Department. Solidarity receives 99 percent of its total revenue from American taxpayers and serves the AFL-CIO, which gave 86 percent of its 2024 political donations to Democrats.

On the climate front: Inflation Reduction Act funds set aside hundreds of billions for the green agenda. A former staffer from an environmental group called the Coalition for Green Capital joined the Biden EPA specifically to direct $27 billion in green funding. Under his tenure, $5 billion was granted to his former organization. Power Forward Communities received nearly $9 billion despite being only a few months old when it applied—and one recipient was a group affiliated with Stacey Abrams that had only $100 in the bank when it received $2 billion.

The Environmental Law Institute, which ran a “Climate Judiciary Project” to educate federal and state judges in favor of climate tort litigation against energy companies, received millions of dollars in grants and contracts from the EPA, the Departments of Justice, Homeland Security, Agriculture, and State, and the National Science Foundation between 2021 and 2024.

Regarding the SPLC specifically: Despite the SPLC reporting $132.7 million in revenue and nearly $770 million in net assets for 2021, the State Department still granted honorariums and speaker fees to SPLC officials. Additionally, a Biden-era Department of Labor approved a $6 million “employment training” grant for NextGen, a nonprofit that fights for “progressive policy change” through advocacy and civic engagement.

The SPLC itself is in the news for separate reasons: the Justice Department indicted the Southern Poverty Law Center on federal fraud charges, alleging it improperly raised millions of dollars to pay informants to infiltrate the Ku Klux Klan and other extremist groups.

The revolving door between these funded NGOs and Democratic administrations is a key part of the story. Personnel from Open Society Foundations and associated left-wing groups cycled in and out of the Biden White House, Justice Department, and other agencies—the same people who had previously shaped grantmaking priorities then directed government money toward aligned organizations.

In just the first month of the Trump administration, 15 groups that had received federal cash from the previous administration sued the current administration, mostly to protect their funding, which totaled $1.6 billion. This is the feedback loop in miniature: government grants activist groups → activist groups lobby for more government → activist groups litigate against anyone who tries to stop it.

Concluding Thoughts

Several converging factors explain the timing of the Treasury Department’s April announcement:

1. Congressional pressure has been building. Multiple House hearings over the past year—the DOGE Subcommittee hearing “Public Funds, Private Agendas: NGOs Gone Wild” and the Judiciary Subcommittee hearing “How Leftist Nonprofit Networks Exploit Federal Tax Dollars”—have built an extensive public record and created political momentum for regulatory action.

2. The rebrand attempt flagged the problem. Arabella’s restructuring into Sunflower Services and Vital Impact in late 2025 was widely seen as an attempt to launder its reputation and escape scrutiny. The Treasury announcement signals that rebranding won’t be sufficient.

3. Form 990 has a structural blind spot. As noted in the Treasury Department’s press release, Form 990 has no mechanism for disclosing fiscal sponsorship activities. This isn’t a bug in enforcement—it’s a gap in the regulatory framework itself, one that has been known and exploited for decades. Treasury is finally moving to close it through regulatory action rather than waiting for Congress to act legislatively.

4.The SPLC indictment and related scrutiny. The indictment of the SPLC, combined with sustained focus on the Tides Foundation’s role in funding anti-Israel groups, has elevated the broader question of nonprofit accountability in the current political moment.

5. The “revolving door” has been documented. The Biden years produced extensive documentation of personnel moving between the dark money network and government agencies, with the explicit effect of directing public funds toward aligned organizations. The Trump administration is using every available tool—executive, regulatory, and prosecutorial—to dismantle these arrangements.

The bottom line is pretty straightforward: for decades, a small number of sophisticated nonprofit aggregators have used fiscal sponsorship to create a system in which billions of dollars—from private megadonors, foreign nationals, and American taxpayers—flow to politically aligned left-wing activist organizations with direct ties to the Democrat Party with essentially no public accountability. The sponsored groups don’t file their own 990s.

The pass-through organizations don’t have to disclose which projects their money supports. And the whole system is perfectly legal under current IRS rules. The Treasury announcement is the first significant regulatory step toward forcing disclosure of these arrangements, and its timing reflects both the political will of the current administration and the groundwork laid by over a year of congressional investigation.
