March 6 (UPI) — U.S. Rep. Tony Gonzales, R-Texas, announced on Friday that he is ending his campaign for re-election after acknowledging an extramarital affair that he had been denying for months.

House Republican leadership called for Gonzales to pull out of the race after the House Ethics Committee said it was investigating the three-term member of Congress over the affair and he then admitted to it on a radio show hours later.

After Tuesday’s primary, Gonzales was to face a runoff for the Republican nomination for his seat after he and YouTuber Brandon Herrera each failed to win more than 50% of the vote.

“After deep reflection and with the support of my loving family, I have decided not to seek re-election while serving out the rest of this Congress with the same commitment I’ve always had to my district,” Gonzales said in a post on X.

“Through the rest of my term, I will continue fighting for my constituents, for whom I am eternally grateful,” he said.

Gonzales has for months been denying he had an affair with his former staffer, Regina Santos-Aviles, 35, in 2024, who later died by suicide after lighting herself on fire.

Gonzales had denied the affair happened since texts were shared by her husband, Adrian, of him asking for a “sexy pic” and her favorite sex position, The Washington Post reported.

Wednesday, not long after the ethics committee announced its investigation, Gonzales said on a radio show that he took “full responsibility for those actions,” admitting to the affair, and said he has reconciled with his wife.

House GOP leadership on Thursday, including Speaker Mike Johnson, R.-La., publicly called for him to end his campaign after the admission.

Herrera’s campaign manager told NBC News in a statement that he appreciated Gonzales for “making the appropriate decision.”

“I look forward to being the voice of TX23 that our district deserves … It’s an honor to be chosen and together we will make Texas proud,” he said in the statement.
