Three Republican-led House committees have threatened ActBlue CEO with contempt of Congress, alleging the Democratic fundraising organization has withheld documents requested as part of an ongoing investigation into fraudulent political donations.

The chairs of the GOP-led committees claim ActBlue "may have deliberately" failed to provide all requested documents in response to a congressional subpoena. The investigation centers on concerns about potentially fraudulent donations processed through the platform.

ActBlue serves as a major fundraising platform for Democratic candidates and causes, processing billions of dollars in political contributions. The platform allows donors to make contributions to multiple candidates and organizations through a single interface.

The congressional probe follows reporting that raised questions about the platform's verification processes and potential vulnerabilities to fraudulent activity. Republican committee leaders are now escalating their demands for documentation from the company.

Contempt of Congress charges can result in criminal referrals, though such cases require approval from the full House and cooperation from the Justice Department for prosecution. The threat represents an escalation in the ongoing investigation into the Democratic fundraising platform's operations.
