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.
