Her daughter was killed in the Uvalde school shooting. Now Kimberly Mata-Rubio is running to be mayor.

Alexandria "Lexi" Rubio loved going to Starbucks and ordering a sweetened tall peach green tea lemonade and a cake pop, showing off bright colors like yellow, pink and turquoise. She wanted to grow up to play softball in college and become a lawyer. But the 10-year-old fourth-grader never got the chance – last May, she was among 21 people killed at Robb Elementary School in Uvalde, Texas. 

Now, her mom is running to be the city's mayor, saying in a message to her daughter, "I will honor your life with action." 

"I grieve for the woman you would have become and all the difference you would have made in this world. I grieve for the woman I was when you were still here," Kimberly Mata-Rubio wrote on X, formerly known as Twitter, on Thursday, along with a photo of a newspaper article announcing her mayoral run. "But, one part of me still exist, I am still your mom."
