This past week, the U.S. Court of Appeals for the D.C. Circuit upheld a decision made by the lower court regarding donor disclosure. This ruling means that a previous regulation by FEC is no longer valid. Now, donors who make contributions over $200 to a nonprofit, 501(c)(4) organization, must be disclosed if their contributions are used for certain political advertising. This political advertising is known as an independent expenditure because it advocates for or against a candidate, but is done by an outside group, not the candidate’s own campaign.
