WASHINGTON — A House GOP chairman is demanding the CEO of ActBlue publicly answer questions about reports that the Democratic fundraising platform loosened fraud safeguards to accept potentially “fraudulent and illegal political donations.”

House Administration Committee Chairman Bryan Steil (R-Wis.) extended an invitation Thursday to ActBlue boss Regina Wallace-Jones to testify on May 19.

“As Chief Executive Officer of ActBlue, the Committee believes you may have information pertinent to its investigation,” Steil wrote in a letter to Wallace-Jones. “Based upon recent reporting, it appears that ActBlue’s production to the Committee’s July 2025 subpoena was deliberately incomplete.”

“There are outstanding questions about whether and how ActBlue has remedied its ‘fundamentally unserious approach to fraud prevention,’” added Steil, citing past letters from his committee compelling lower-level officials to testify.

ActBlue reps have maintained that the platform has “always been forthcoming with Congress” and denied allegations of fraud — including possible contributions from foreign donors.

Attorneys for Dechert LLP, which is now representing ActBlue, accused the three GOP committees investigating the platform in a Thursday letter of continuing a “partisan attack on a political opponent” during an election year.

The lawyers said that “Republican congressional leadership has singled out ActBlue not because of any alleged wrongdoing, but because Republicans see a political advantage to undermining the nonprofit that powers thousands of Democratic candidates and causes at every level.”

“This concern is compounded by the Committees’ conspicuous failure to scrutinize the widely reported deficiencies in the donor verification practices of WinRed, ActBlue’s Republican fundraising counterpart that members of the committee rely on for their own campaigns,” they added.

“These actions are particularly troubling in light of President Trump’s directive to the Justice Department to investigate ActBlue.”

Along with the Oversight and Judiciary Committees, Administration’s GOP members and staff have been investigating ActBlue for around two years about its shifting fraud-prevention standards in the lead-up to the 2024 presidential election.

That’s resulted in subpoenas for testimony from current and former ActBlue officials and attorneys — all five of whom invoked their Fifth Amendment right against self-incrimination in depositions before the House Republicans last year.

The House GOP chairmen — including Reps. James Comer (R-Ky.) and Jim Jordan (R-Ohio) — have also accused ActBlue of failing to hand over documents responsive to their probe after a bombshell New York Times report earlier this month.

Covington & Burling, which had been representing ActBlue in early 2025, said in one memo exposed by the report that it could be “alleged that ActBlue accepted and/or facilitated the acceptance of foreign national contributions into American elections.”

The five ActBlue employees took the fifth 146 times after internal records, first reported by The Post, showed the left-wing fundraising juggernaut made donation standards “more lenient” twice during the 2024 cycle.

Before January 2024, the platform also allowed contributions made via credit, prepaid debit and gift cards — without requiring a Card Verification Value (CVV).

“In 2025, in response to this partisan investigation, ActBlue also cut off all donations from American citizens abroad,” Dechert attorneys said.

Texas Attorney General Ken Paxton sued the platform on Monday after investigators in his office were able to make donations by providing CVVs while allegedly using fake identities.

“The Committee is considering potential legislative reforms to address fraudulent and illegal political donations made using online fundraising platforms such as ActBlue,” Steil noted, asking for Wallace-Jones to confirm attendance by April 30.

A House GOP aide previously noted that all options were “on the table” — including a subpoena for Wallace-Jones’ testimony or even contempt of Congress proceedings.

Dechert attorneys in their letter said that “ActBlue has cooperated with the Committees’ politically motivated investigations for more than two years.”
