PHOENIX — Nearly a year after the 2020 election, Arizona’s then-attorney general, Mark Brnovich, launched an investigation into voting in the state’s largest county that quickly consumed more than 10,000 hours of his staff’s time.
Investigators prepared a report in March 2022 stating that virtually all claims of error and malfeasance were unfounded, according to internal documents reviewed by The Washington Post. Brnovich, a Republican, kept it private.
In April, the attorney general — who was running in the GOP primary for a U.S. Senate seat — released an “Interim Report” claiming that his office had discovered “serious vulnerabilities.” He left out edits from his own investigators refuting his assertions.
Brnovich launched the investigation shortly after Cyber Ninjas, a Florida-based firm hired by the GOP-led state Senate, ended its own review of the election in September 2021. The months-long legislative review, which was roundly criticized by election experts, affirmed Trump’s loss in the state.
