Sept. 24 (UPI) -- Adelita Grijalva, a county supervisor, claimed victory late Tuesday in the special election to fill Arizona's 7th Congressional District, further shrinking the Republicans' majority of the House of Representatives.

"Thank you, #AX07," she said on X, "We made history -- juntos. Now, let's get to work!"

Grijalva, 54, was widely expected to beat Republican Daniel Butierez, 58, for the seat left vacant in March following the death of her father, Raul Grijalva, the 77-year-old congressman who died from complications of cancer.

Unofficial election results from the office of Secretary of State Adrian Fontes show Grijalva trounced Butierez, securing more than 70% of the vote compared to his 28%.
