While much of the funding to the “dark money” behemoths tied to the leaders of Congress remains a mystery, a review of corporate disclosures reveals more of the companies that have donated.

The four nonprofits tied to the highest-ranking Democrats and Republicans in Congress have in recent election cycles been among the largest spenders on congressional elections, but they are not required to disclose their donors so almost no one knows from where the bulk of their funding has come.
However, more large American companies have begun voluntarily disclosing their political donations due to pressure from shareholder activists, and some are disclosing money they give to so-called “dark money” 501(c)(4) nonprofits that do not disclose their donors. By reviewing hundreds of corporate disclosures, lobbying contribution filings, and other documents, Sludge has identified more than two dozen companies that have donated to the nonprofits linked to congressional leaders, either directly from their corporate treasuries or through their PACs.

The four nonprofits are Majority Forward, a pro-Senate Democrat nonprofit with ties to Senate Majority Leader Chuck Schumer (D-N.Y.); One Nation, a pro-Senate Republican nonprofit with ties to Senate Minority Leader Mitch McConnell (R-Ky.); House Majority Forward, a pro-House Democrat nonprofit with ties to House Minority Leader Hakeem Jeffries (D-N.Y.); and American Action Network, a pro-House Republican nonprofit with ties to House Speaker Kevin McCarthy (R-Calif.).
