Fact Check: Did Kathy Castor repeatedly violate the STOCK Act?

Media Bias Fact Check (MBFC) publishes daily vetted fact checks from verified IFCN-approved sources. Each claim is independently reviewed for accuracy and context.


Claimant: Club for Growth Action


Claim: U.S. Rep. Kathy Castor “repeatedly” violated “a law aimed at stopping members of Congress from insider trading.”


Rating: MOSTLY FALSE


Explanation: Castor filed two reports in 2017 that disclosed three stock trades late. However, the ad’s principal 2021 example resulted from an erroneous filing that Castor corrected within days, showing the trades had actually been reported on time. PolitiFact found no evidence that she engaged in insider trading or misused confidential information.
