The head of ActBlue, the Democratic fundraising giant, plans to invoke the Fifth Amendment during testimony before Congress on Wednesday.
The decision comes amid reports that lawmakers are investigating whether the organization misled Congress regarding how it screens foreign donations.
ActBlue is a major platform for small-dollar Democratic donors, raising hundreds of millions of dollars each election cycle.
The congressional inquiry focuses on allegations that ActBlue may have failed to properly vet contributions from foreign nationals, which is illegal under federal campaign finance law.
The CEO’s refusal to testify under oath marks a significant escalation in the ongoing dispute between the committee and the organization.
ActBlue has denied any wrongdoing and maintains that it complies with all federal campaign finance regulations.
The company has not publicly commented on the specific allegations at the center of the investigation.
