A former Arizona Democratic candidate now finds herself on the other side of the justice system after police say she forced her way into an ex-partner’s Phoenix home while armed with a knife and black tape. The woman, a one-time party leader, is facing felony assault and burglary charges plus a misdemeanor, has been released on bond, and is set for a preliminary hearing on Monday.

Police account and charges

Phoenix police say the confrontation started around 6 p.m. on July 10 in a neighborhood near Indian School Road and Interstate 17. When the victim opened the door, officers say the suspect shoved her way inside.

According to a probable-cause statement, the suspect was holding a knife in one hand and black tape in the other. The report says she struggled with the victim until the victim pushed her onto a couch, and that she then made a lunging motion with the knife toward two other women in the home before running off.

Officers later went to the suspect’s downtown Phoenix residence, executed a search warrant, and reported finding a knife, tape, and gloves. Court records show she was booked on aggravated assault using a simulated deadly weapon, third-degree burglary, and misdemeanor disorderly conduct, then released on a $15,000 bond, according to Phoenix New Times.

Who is Brianna Westbrook?

The suspect is identified in the arrest report as Brianna Westbrook, a transgender-rights organizer who has served as a vice chair of the Arizona Democratic Party and has run for both state and federal office. Her past campaigns include multiple bids for the state legislature and a 2018 run for Congress, making her a familiar name in local progressive circles.

Details on Westbrook’s political roles and candidacies are documented in public candidate profiles such as BallotReady.

Her version and what she told police

According to court records cited by local reporters, Westbrook told officers that she and her former partner were “into BDSM,” that the knife was fake, and that the visit was a prearranged re-enactment meant to help the alleged victim confront past trauma.

The alleged victim, however, told police she had not agreed to any such re-enactment. A police release questionnaire also flagged a reported history of domestic violence in the relationship and noted concerns about increasing frequency or intensity.

Westbrook did not respond to messages seeking comment. While officers were surveilling her home, they wrote that she made “spontaneous utterances” referring to the situation as a “big misunderstanding,” according to Phoenix New Times.

Legal context and next steps

Under Arizona law, aggravated assault committed with or by a simulated deadly weapon is classified as a class 3 felony, while burglary in the third degree is generally a class 4 felony. Those classifications help determine potential sentencing ranges if a conviction is ultimately returned. The relevant statutory language appears in A.R.S. 13-1204 and A.R.S. 13-1506, as published by CaseMine and Justia.

For now, the case sits on the Maricopa County Superior Court calendar. Westbrook is due back in court for a preliminary hearing Monday, where a judge will decide how the case moves forward.
