Minneapolis is again confronting upheaval at the top of its police department. Police Chief Brian O’Hara resigned on May 26 after Mayor Jacob Frey said investigators found he interfered with an inquiry into allegations about his personal conduct.
Resignation follows mayor’s finding of a breach of trust
Frey announced Tuesday evening, May 26, that O’Hara had stepped down rather than face disciplinary action that could have included termination. According to the mayor, investigators did not substantiate the underlying allegations that O’Hara had engaged in intimate relationships with city employees, but they did conclude that he interfered with the investigation into those claims. Frey said that interference, not the unproven original allegations, made it impossible for O’Hara to continue leading the department.
In a written reprimand described by multiple outlets, Frey said O’Hara had “knowingly and intentionally” deleted a contact card from his city-issued phone in an effort to shield evidence of his connection to a city employee. The reprimand also said O’Hara told another city employee about the investigation after being instructed to keep the matter confidential. Frey framed the conduct as a serious violation of trust for the leader of the city’s largest law enforcement agency.
“Everyone makes mistakes, including me, but what I can’t allow is a breach of trust,” Frey said at a news conference reported by CBS Minnesota. He added that, for a Minneapolis police chief, trust is not just part of the job but central to it. That message was repeated in the mayor’s explanation that discipline was warranted even though the underlying misconduct allegations were not sustained.
The resignation landed suddenly because Frey had only weeks earlier re-nominated O’Hara for another term. That timing quickly fueled criticism from some City Council members and raised questions about what city leaders knew, when they knew it, and how long the inquiry had been underway. By late Tuesday, the city had moved to install Assistant Chief Katie Blackwell as acting chief effective immediately.
A chief hired to stabilize a troubled department exits abruptly
O’Hara arrived in Minneapolis in late 2022 as an outsider with a reform mandate and a difficult assignment. The city was still reeling from the May 25, 2020 murder of George Floyd by then-Officer Derek Chauvin, a killing that triggered global protests and brought intense scrutiny to the Minneapolis Police Department. The department was also dealing with depleted staffing, low morale and multiple federal and state oversight pressures.
Before coming to Minneapolis, O’Hara had spent much of his career in Newark, New Jersey, where he gained notice for work on policing changes after that city’s own federal consent decree. Frey presented him as an experienced reformer who could help rebuild a department that had lost hundreds of officers and become a symbol of police misconduct nationally. His appointment was seen as a major personnel decision in Minneapolis’ long effort to demonstrate that it could change police culture while maintaining public safety.
During his tenure, city leaders and O’Hara pointed to some improvements in recruiting and crime trends. His supporters also credited him with guiding the department through politically fraught moments, including recent tensions tied to federal immigration enforcement activity in Minneapolis. In public, Frey had continued to back him. On May 6, the mayor re-nominated O’Hara, calling him the right leader for the moment.
That endorsement now looks striking in light of the resignation just 20 days later. AP and local reports described a scenario in which the city quietly dealt with new evidence and an investigation into whether O’Hara had obstructed an earlier probe. The sudden collapse of the chief’s tenure leaves Minneapolis once again searching for stable leadership at a time when residents, officers, elected officials and outside monitors are all watching the department closely.
Questions mount over the investigation and city oversight
Much of the immediate fallout has centered on how the case was handled inside city government. According to reports from AP, CBS Minnesota and the Star Tribune, the allegations against O’Hara involved claims that he had engaged in intimate relationships with city employees. Those allegations were investigated and ultimately not substantiated, but the later inquiry focused on whether he tampered with evidence and compromised the integrity of that process.
The reported deletion of a contact card from a city-issued phone became one of the central findings. Investigators also concluded that O’Hara disclosed the existence of the investigation to another city employee after being instructed not to do so. In the view of the mayor, those acts damaged confidence in the fairness and independence of the review. That distinction matters legally and politically: a person can avoid substantiation on the original accusation yet still face consequences for obstructing the investigation itself.
City Council members quickly pressed for more transparency. Some said they were not briefed even as the mayor moved earlier this month to renominate O’Hara. That gap prompted criticism that the council was sidelined on a matter involving one of the city’s most important public officials. The dispute also revived long-running tensions between Frey and progressive council members over police governance, accountability and the pace of reform.
The case may not end with O’Hara’s resignation. Local reporting has indicated that other employees connected to the matter have come under scrutiny as investigators examine witness contact and possible intimidation. Even without criminal charges announced so far, the episode is likely to spur calls for tighter rules around internal investigations, handling of city-issued devices and disclosure obligations for top officials. In a city with deep mistrust of police oversight systems, process can be as politically consequential as outcome.
Why the resignation matters beyond one personnel scandal
The significance of O’Hara’s departure extends well beyond a single misconduct case because Minneapolis remains under extraordinary pressure to transform its police department. The U.S. Department of Justice and the Minnesota Department of Human Rights previously found patterns of excessive force, discriminatory policing and accountability failures within MPD. Those findings put city leaders under continuing obligation to show that reforms are real, durable and enforced from the top down.
That is why allegations of interference by the chief carry such weight. Reform efforts depend heavily on whether the public believes top officials are held to the same or a higher standard as rank-and-file officers. If the chief of police is seen as manipulating an internal inquiry, it undercuts repeated city assurances that Minneapolis has learned from past failures. It also creates new headaches for a department trying to recruit officers, maintain morale and persuade skeptical residents that its culture is changing.
The resignation also comes at a politically sensitive time for Frey. The mayor has positioned himself as both a defender of public safety and a leader committed to police reform. O’Hara was central to that balancing act. Losing him under these circumstances exposes Frey to criticism from multiple directions: from those who say he moved too slowly and from those who argue the city cannot afford another leadership crisis at MPD.
For residents, the episode may reinforce a broader sense of instability that has defined city politics since 2020. Minneapolis has experienced clashes over use of force, staffing levels, protest response, federal oversight and the future structure of policing itself. O’Hara had been hired to project steady management amid that turbulence. His resignation instead adds another layer of uncertainty to a department whose leadership changes carry consequences for public confidence far beyond City Hall.
What comes next for Minneapolis and the police department
In the short term, Assistant Chief Katie Blackwell has taken over as acting chief, giving the city an experienced internal figure to maintain daily operations. Blackwell is a longtime department leader and familiar face in Minneapolis policing, which could provide continuity at a moment of institutional shock. But acting leadership is not the same as a permanent solution, especially in a department facing scrutiny from elected officials, community activists and outside regulators.
The next steps are likely to unfold on two tracks. One is administrative: city leaders must decide whether to launch a national search, elevate from within or undertake some other process for naming the next chief. The second is political and investigative: the council, mayor’s office and public will continue to demand a clearer accounting of how the O’Hara matter developed, why the mayor re-nominated him while questions were unresolved, and whether city oversight mechanisms worked as intended.
O’Hara’s own camp has sought to defend his broader record. A statement released through his attorney after the resignation highlighted his work to reduce violent crime, rebuild staffing and guide Minneapolis through one of the most difficult periods in its recent history. That defense suggests the battle over his legacy will not be limited to the specific findings in the investigation. Supporters are likely to argue that a chief brought in to manage crisis should not be defined solely by the circumstances of his departure.
Still, in public office, endings matter as much as beginnings. O’Hara was recruited to help Minneapolis restore faith in a police department scarred by scandal and global notoriety. His resignation on May 26, 2026, after findings that he interfered with an investigation into his own conduct, ensures that his tenure will be judged not only by policy goals and crime data, but by the question Minneapolis has asked repeatedly in recent years: whether those in power can be trusted to police themselves.
