Wallace-Jones had originally agreed to testify voluntarily before Congress concerning ActBlue's vetting process for foreign contributions to domestic candidates. But her attorneys requested a congressional subpoena on Monday, ahead of her June 10 testimony, according to committee lawmakers.

The House asked Wallace-Jones to testify after a recent New York Times report included memos from Covington & Burling, a law firm that worked for ActBlue, warning that she may have misled Congress about the process for screening overseas donations.

ActBlue is the dominant Democratic fundraising platform. In 2025 alone, the platform reported raising almost $1.8 billion from 52 million contributions, and Q4 that year marked the single-largest off-cycle quarter in ActBlue history.

Under federal election law, foreign nationals or those who are not permanent residents are forbidden to donate directly to federal candidates or political action committees.

Administration Committee Chairman Bryan Steil (R-Wis.) said only Americans should decide their elections during the hearing titled, "Preventing Fraudulent Donations: Transparency, Verification, and Accountability."
