David Schweikert (@RepDavid) January 13, 2026 The Associated Press shared further: Colleagues and friends of Brnovich praised him for his work in public service that included stints as a judge, a prosecutor, lawyer and the director of the Arizona Department of Gaming. Former Republican Arizona Gov. Doug Ducey said Brnovich’s passion for the law, justice and victims were hallmarks of his career. “For those of us blessed to call him a friend, his humor, positivity, and happy warrior spirit were infectious. May he rest in peace,” Ducey said on the social platform X. Brnovich, a Republican, was in his second term as attorney general in Arizona when his office investigated the 2020 election. Arizona was among the states Joe Biden won that year to deny Trump reelection to the presidency. Brnovich released an interim report in April 2022 that outlined his concerns with some election procedures but did not provide any proof of major issues despite six months of investigation. At the time, Brnovich was seeking the Republican nomination for a U.S. Senate seat and facing fierce criticism from Trump, who claimed he wasn’t doing enough to prosecute election fraud. Brnovich wanted an endorsement from Trump but didn’t get it.
