The billionaire’s Open Society Action Fund donated $1 million in 2023 to the Congressional Integrity Project, a group that received nearly all of its war chest in prior years from the Sixteen Thirty Fund, a Democratic dark money organization in Washington, D.C., the records show. The grants were earmarked “to support nonpartisan advocacy on congressional accountability,” according to the funding database for the Soros-funded Open Society Foundations philanthropy network.

News of the $1 million cash infusion from Open Society Action Fund provides an inside look at how Soros helped to keep the lights on for a Democratic strategist-led entity that established itself as a key attack dog against the GOP’s House majority, particularly House Oversight Committee Chairman James Comer (R-KY) and House Judiciary Committee Chairman Jim Jordan (R-OH). Comer and other lawmakers spent much of this Congress looking into the foreign business dealings of Hunter Biden, the 54-year-old son of President Joe Biden.

But the investigation struggled to gain bipartisan credibility amid setbacks and a razor-thin GOP majority that Democrats said focused on “fruitless” allegations of wrongdoing. House Republicans released their findings from a yearlong impeachment inquiry into the president in August, concluding that his family and business associates raked in over $27 million in connection to foreign business deals. However, the report stopped short of recommending that the House proceed to impeach the president and did not identify criminal wrongdoing.

“It comes as no surprise that a radical left-wing dark money group is funded by George Soros to attack Republicans who have been at the forefront of exposing the Biden-Harris administration’s radical agenda and the Biden family’s corrupt influence peddling racket,” Comer told the Washington Examiner.

“Republicans have fought to bring transparency to the Swamp, but the Congressional Integrity Project is trying to keep its funding hidden from the American people,” Comer said. “We will keep fighting for transparency and accountability in Washington regardless of CIP’s efforts to keep Americans left in the dark.”

In a statement to the Washington Examiner, an Open Society Foundations spokesperson said: “We are proud to support the Congressional Integrity Project’s work to make sure that congressional oversight serves the public interest, rather than partisan interests.”

The CIP says on its website that it is “committed to exposing the reality behind Republicans’ politically motivated oversight and investigations targeting President Biden and Democrats.” It is registered under a section of the IRS code called 501(c)(4) that allows groups to receive tax-exempt status so long as they operate to promote “social welfare.”

The CIP’s 501(c)(4) status means it does not have to disclose its donor to the IRS. Open Society Action Fund is also registered under this section of the IRS code.

The Washington Examiner reported in December 2022 on how the CIP’s revenue came almost entirely from the Sixteen Thirty Fund from 2020 to 2021. The Sixteen Thirty Fund, a 501(c)(4) nonprofit group, is one of several entities connected to Arabella Advisors, a consulting firm doubling as the largest Democratic-aligned dark money network in the United States.

The CIP’s ties to the LLC’s shadowy network extend further. Kyle Herrig, the director of the CIP, is the founder of an organization called Accountable.US that used to be under the umbrella of the New Venture Fund, a 501(c)(3) charity managed by Arabella Advisors, according to tax records.

The Soros-backed Open Society Foundations is a substantial funder of projects managed by the New Venture Fund, tax records show. Soros has long given generously to Democrats and left-leaning causes related to criminal justice, immigration, climate, and other issues, according to Federal Election Commission filings and tax documents.

The CIP did not return a request for comment.
