Kimberly Peeler-Allen, a board member of ActBlue, invoked her Fifth Amendment right during closed-door testimony as part of a joint House investigation into the Democratic fundraising platform over allegations of illicit foreign donations and inadequate fraud prevention. She is the third senior ActBlue figure to decline to answer questions on the record, following co-founder Matt DeBergalis and chief executive Regina Wallace-Jones, deepening Republican frustration with the organisation's lack of cooperation.

The probe, led jointly by the House Administration, Judiciary and Oversight Committees, stems from a 2023 inquiry by Administration Chairman Bryan Steil into whether ActBlue's failure to require credit card CVV numbers left it exposed to foreign or fraudulent contributions. ActBlue, which has raised roughly $20 billion for Democratic campaigns and causes since its founding, has faced further scrutiny after a New York Times report suggested Wallace-Jones may have misled Congress by describing the platform's donor-screening process as "multilayered" despite legal advice that its own procedures were not consistently followed. Steil has rejected claims the investigation is partisan, framing it as a broader review of fraud safeguards across online fundraising platforms.
