Minnesota Gov. Tim Walz is the running mate of Democratic presidential nominee Vice President Kamala Harris and could potentially be the nation's next vice president, but not everybody is happy with the job he's done thus far in his current position.

It was recently discovered that the rooftop of the Minnesota governor's mansion, which is currently unoccupied as it undergoes renovations, was vandalized with graffiti that declares "Walz Failed" in giant letters, according to CBS News.

State and local police are reportedly investigating the incident but have released no other details about who may be responsible or when the vandalism occurred.

Anti-Walz graffiti only visible from the air

The Minnesota Star Tribune reported this week on graffiti that was spotted on the rooftop of the governor's mansion in St. Paul and joked that the minor vandalism must have been perpetrated by a "timid tagger," given that only "birds, HVAC repair technicians, and drone operators" would be able to see it.

In large black letters spray painted on top of an industrial-sized white air conditioning unit was a simple message that read "Walz Failed," which was spotted and shared on social media by a local photojournalist named Chad Davis.

It is unclear when, exactly, the vandalism occurred, but Gov. Walz and his family definitely weren't there whenever it happened, as they have instead been residing elsewhere since last year while the historic building has undergone a $6.3 million renovation project.

That ongoing renovation has included scaffolding surrounding the governor's residence, which likely explains how someone was able to gain access to the rooftop to leave the anti-Walz message.

"Walz Failed" a common slogan of the governor's critics

According to local Fox affiliate KMSP, Gov. Walz and his family moved out of the governor's mansion in July 2023 and have since then been residing at Eastcliff Mansion, a large residence owned by the University of Minnesota that typically houses the school's president but was temporarily leased to the state for the First Family by the university's board of regents last year.

That lease was supposed to expire in September but the renovation project on the governor's mansion has continued past the deadline and it remains unclear when it will be finished -- though cleaning the graffiti off the rooftop A/C unit shouldn't add to any further delays.

The outlet noted that the "Walz Failed" message has been adopted as a sort of unofficial slogan of the governor's political opponents, in large part over disagreements with how he handled the 2020 COVID-19 pandemic with lockdowns and other harsh restrictions in contrast with his hands-off approach to the disruptive and destructive George Floyd anti-cop protests and riots that erupted in May of that same year, left Minneapolis in smoldering ruins with a demoralized police force, and subsequently swept through other major cities across the country after the unrest was left unchecked.

Police are investigating

Local ABC affiliate KSTP similarly reported that the "Walz Failed" message has been championed by the governor's critics and has been often seen around the state over the past few years, including in ads, on billboards, and even at the state fair.

In response to the vandalism, the Minnesota State Patrol said in a statement, "The Saint Paul Police Department and the Minnesota State Patrol are currently investigating who defaced equipment at the Governor’s residence and when it happened."

"No one is currently living at the residence while it is under construction. The agencies aren’t going to speak to specific security procedures and will not speculate on any aspects of this ongoing investigation," the statement added.
