Texas Attorney General Ken Paxton used a Collin County address to vote in six elections over the past two years, including the May Republican Senate runoff, while reporting links him to a Denton County home. This occurred after his office issued guidance ahead of primary elections stating, "You must register to vote using the address where you reside."

State Senator Angela Paxton, who filed for divorce from Ken Paxton in 2025, stated in her filing that Ken Paxton had moved out of their Collin County residence a year prior. Reporting by ProPublica and The Texas Tribune linked Ken Paxton to a Denton County home, which a trust purchased earlier in the year. Ken Paxton is not registered to vote in Denton County. Three election lawyers stated that Ken Paxton may have violated Texas law regarding voter residency. Campaign spokesperson Madison Cercy described the report as a "baseless, lie-filled tabloid story" and stated that Ken Paxton "is a lawful, registered Texas voter in full compliance with the law."

Interior photographs from a real estate listing of the Denton County home match the background seen in a podcast appearance Ken Paxton made in June 2026. A reporter found mail addressed to "Warren Paxton" in the mailbox of the Denton County home in June 2026. Angela Paxton stated through a spokesperson that she has no connection to the Denton County home or the trust that purchased it.

David Becker, director of the Center for Election Innovation and Research, said, "There would be questions raised about a residence where someone does not live, does not spend the night and can in no way have the intent to continue to reside." Paxton's office guidance also stated, "It is illegal to misrepresent your residence on election records or to establish a residence for the purpose of influencing the outcome of an election." Voting in an election when ineligible is a second-degree felony in Texas, punishable by up to 20 years in prison and a $10,000 fine.

Ken Paxton won the Republican nomination for U.S. Senate in a May runoff election and received an endorsement from President Donald Trump. He faces Democrat James Talarico in the U.S. Senate race in November. President Donald Trump posted on Truth Social: "Ken is a true MAGA Warrior who has ALWAYS delivered for Texas, and will continue to do so in the United States Senate." Ken Paxton has faced felony securities fraud charges, was subject to an FBI investigation into corruption, and was acquitted in state impeachment hearings. The State Bar of Texas brought a case against Ken Paxton for his efforts to overturn the results of the 2020 presidential election.
