Yee filed the complaint in September, alleging that Ruiz broke the law by featuring public school staff and students in campaign materials. At the time, Ruiz dismissed the allegation as "meritless" and "desperate," explaining that she had visited schools to hear directly from educators about their priorities.

The county attorney's office determined that publishing photos and videos of a candidate's appearance at a school after the visit does not break the law, according to Ruiz's campaign.

"From the beginning, this was a baseless political attack designed to distract from the issues that matter to Arizona students and families," Ruiz said in a news release. "The law was clear, and the outcome was never in doubt. Throughout this campaign, I have remained focused on Arizona's students, educators and families and that is exactly where my attention will remain."

Ruiz also characterized the complaint as an attempt to divert attention from negative press Yee received after raising debunked claims about schools accommodating students who identify as furries with litter boxes during a Legislative District 3 meeting in February. Fact-checkers have found no evidence to support such claims.

Ruiz defeated Yee last week in the race for Arizona superintendent of public instruction. Her campaign noted that Yee has not yet conceded and is the only statewide candidate who has declined to do so.

With the complaint resolved, Ruiz said she is turning her attention to preparing to run the Arizona Department of Education. She is meeting with outgoing Superintendent Tom Horne to ensure a smooth transition when she takes office in January.

Once in office, Ruiz plans to prioritize public education, support teachers, expand opportunities for students and bring accountability to the Empowerment Scholarship Account program, the state's school voucher system.

The dismissal marks a conclusion to a contentious post-election dispute and clears the way for Ruiz to focus on her transition and policy agenda ahead of the January inauguration.
