AUSTIN, Texas — Kimberly Mata-Rubio, the mother of Alexandria “Lexi” Rubio who was killed in the Uvalde, Texas, school shooting last year, announced Thursday that she is running to be the Texas city’s next mayor.

Mata-Rubio, 34, is seeking to succeed Mayor Don McLaughlin, who is stepping down after nearly 10 years leading the city to pursue a seat in the Texas House. A special election for mayor will be held on Nov. 7.

Mata-Rubio made the announcement on X, the social media platform formerly known as Twitter. Addressing her daughter, one of 19 fourth-grade students killed in the May 24, 2022, massacre, she wrote: “I will honor your life with action. This is only the beginning.”

Mata-Rubio and Cody Smith, a banker and former mayor, are the only two candidates who’ve publicly announced a bid for the city’s top elected office.

“I want to represent the underserved in this community, whose voices matter but have long been unheard. I want residents to see themselves in me and feel at ease sharing their grievances,” Mata-Rubio told the Uvalde Leader News when announcing her campaign.
