Texas Attorney General Ken Paxton filed a lawsuit Monday in Tarrant County Court against ActBlue under the Deceptive Trade Practices Act. The suit asks a judge to stop the platform from accepting donations made through gift cards and prepaid debit cards and to impose fines of $10,000 for each violation.

Paxton alleges that ActBlue allows improper donations from people outside the United States and from donors who have already reached mandated contribution limits. ActBlue is the main fundraising platform used by Democratic candidates and causes, and it processed $1.78 billion last year, with more than 28 million people having donated through it since its founding.

Paxton opened an investigation into ActBlue in December 2023. In early 2024, he sent a letter to the Federal Elections Commission claiming he had uncovered evidence that "bad actors can illegally interfere in American elections by disguising political donations," Paxton wrote. In August 2024, he said ActBlue had agreed to begin requiring CVV codes on credit card donations.

In April 2025, President Trump ordered the Justice Department to investigate ActBlue. Paxton later involved ActBlue in his investigation of Texas Democratic House members who left the state in the summer of 2025 to protest mid-decade redistricting.

ActBlue has denied wrongdoing throughout the investigations. ActBlue said, "Partisan allegations against ActBlue are completely baseless. Let's be clear: Donald Trump and his accomplices in the Republican party are targeting ActBlue as part of their brazen attack on democracy in America."

ActBlue spokesperson De'Andra Roberts-LaBoo addressed the Texas filing directly. "This is a thinly veiled attempt to distract from Ken Paxton's numerous legal and ethical issues ahead of next month's runoff. If he and his Republican allies actually cared about donor fraud, they would work to strengthen security standards across the board, including within their own operations, rather than targeting ActBlue," Roberts-LaBoo said.

The New York Times reported earlier this month that ActBlue lawyers raised concerns that the company's systems were not as robust as top executives had told congressional Republicans. Paxton filed Monday's lawsuit in Tarrant County, where the case will be heard by a state court judge.
