A former political candidate who ran campaigns for both state and federal races in Arizona was arrested for an alleged disturbance that happened in an area of the state known as the Valley. Brianna Westbrook, 41, was taken into police custody on July 10, 2026, after her former partner called local law enforcement following an incident that took place at a residence in the city of Phoenix.
The individual who reported Westbrook spoke with the cops and said that she allegedly “pushed her way” into the home while in possession of a knife and duct tape. The two allegedly wrestled with each other until Westbrook managed to push the other individual involved in the situation onto a couch. The victim in the assault screamed and asked Westbrook “to stop” before the suspect eventually took off running.
When officers detained Westbrook, she attempted to downplay the violent altercation, claiming it was a “big misunderstanding.” She then told officers that the incident at her former partner’s residence was part of a “scene” the two were acting out. However, the victim told police a different story, saying they never agreed to recreating a “scene.”
Westbrook elaborated that she had a knife and tape because the two of them were “into BDSM,” according to an article from the Phoenix New Times. She also said the scene the two were acting out was an “agreed to re-enact a scene where Westbrook scares the victim to help her deal with prior childhood trauma of abuse” and that the victim agreed to it via a “subliminal message on Instagram.” The suspect also claimed the knife was fake.
According to a report from News 12, officers allegedly found “a knife, duct tape, and gloves” after they were granted a search warrant. Westbrook was then booked into the county jail and issued a $15,000 bond. The suspect had formerly served as the vice chair of the Arizona Democratic Party and has run for office several times. She ran unsuccessfully for a congressional seat in 2018.

The seat was eventually won by Republican Debbie Lesko. In 2022, Westbrook also lost the Democratic Party primary race for Arizona’s 5th Legislative District. Westbrook broke into the political scene after becoming the highest-ranking transgender individual in the state Democratic Party. The suspect was nominated in 2024 to fill an empty legislative seat, however she was ultimately not appointed by the county board of supervisors.
A questionnaire connected with Westbrook’s arrest reveals that police checked several boxes saying that the suspect had a history of domestic violence and that the “frequency/intensity” of that violence was increasing. However, records obtained from the Maricopa County Superior Court show that Westbrook had no previous criminal charges.
Westbrook was also an organizer for the Democratic Socialists of America (DSA) which is a political group that has been growing in popularity in recent years, especially due to the election of Zohran Mamdani as mayor of New York City. Several other DSA members have unseated incumbents in local New York politics, moving on to the general election in November.
