Trump didn’t hold back.

More than 30 community water systems across Minnesota were targeted in a coordinated cyberattack, raising fresh concerns about the security of America’s critical infrastructure. But while some officials have pointed to possible Iranian involvement, President Donald Trump says the real problem lies much closer to home: Minnesota Gov. Tim Walz and his administration.

Speaking during a Cabinet meeting Friday at Camp David, Trump forcefully rejected early speculation that Iran was solely to blame for the attacks, arguing that Minnesota’s leadership deserves the greatest scrutiny.

“They say Iran did it. I don’t think so,” Trump said. “I blame Minnesota because they’re grossly incompetent. I blame the corrupt governor of Minnesota. Iran has much bigger problems than worrying about Minnesota.”

Trump’s remarks immediately reignited criticism of Walz, whose administration has faced years of questions over oversight failures involving several high-profile fraud scandals and the management of state programs.

Trump Questions Early Cyberattack Claims

The president’s comments came after reports suggested investigators were examining whether Iranian-linked hackers were responsible for the attacks on Minnesota’s water infrastructure.

However, officials have not publicly identified a specific group responsible, and the investigation remains active. Minnesota IT Services said it has not yet determined who carried out the coordinated attack.

The agency confirmed that operational technology at more than 30 community water systems was targeted over a two-day period. Despite the disruptions, officials stressed there is no indication that drinking water has been contaminated or that residents need to alter their water usage.

Several Cities Forced Into Manual Operations

The cyberattack interrupted automated systems at several Minnesota communities, forcing local officials to activate backup procedures to keep water treatment facilities operating safely.

In Braham, malicious software temporarily shut down controls for both the city’s well and water treatment plant. Plymouth and South St. Paul also shifted portions of their operations to manual control while technicians worked to restore normal service.

Officials emphasized that no known threat to public drinking water has been identified, but the incident underscored the growing vulnerability of critical infrastructure to sophisticated cyberattacks.

Trump Renews Criticism Of Tim Walz

For Trump, the cyberattack quickly became another example of what he describes as failed leadership in Minnesota.

The president has repeatedly criticized Walz over fraud scandals that occurred during his time as governor, including widespread abuse within state-administered social service programs. Although Walz has never been accused of personally participating in those schemes, Republicans have argued that the scandals exposed serious weaknesses in oversight and accountability under his administration.

Walz, who was the Democratic nominee for vice president in 2024, announced earlier this year that he would not seek a third term as governor following increased political scrutiny surrounding his administration.

Trump has frequently pointed to Minnesota’s fraud cases as evidence that stronger leadership and tighter government oversight are needed.

Walz Pushes Back

Walz responded to Trump’s criticism in a post on X, arguing that the president was ignoring the broader national security implications of the cyberattack.

The governor said Trump knows multiple states have experienced similar incidents and argued that attacks on critical infrastructure represent a growing challenge facing the United States.

Walz maintained that cyberattacks targeting essential public services demonstrate how modern warfare is increasingly being fought through digital networks rather than conventional battlefields.

Federal Agencies Warned About Infrastructure Threats

Just days before the attacks in Minnesota, federal cybersecurity officials issued a warning that hackers linked to Iran were attempting to infiltrate the computerized control systems that operate water utilities, power infrastructure, and local government networks across the United States.

According to the warning, the cyber campaign had already disrupted operations at several organizations and caused financial losses. Investigators said the attacks appeared designed to create disruption inside the United States by targeting essential public infrastructure.

Security experts have also noted that many successful cyber intrusions exploit outdated technology, internet-connected equipment and weak cybersecurity practices, including default or missing passwords.

Iran Has Been Linked To Similar Attacks Before

While investigators have not reached a final conclusion about the Minnesota cyberattack, Iran has previously been linked to attempts to compromise American water infrastructure.

In 2023, U.S. cybersecurity officials reported that hackers linked to Iran’s Islamic Revolutionary Guard Corps infiltrated programmable control systems at several American water and wastewater facilities. Investigators found that many of the breaches were made possible because internet-connected devices were protected by weak, default, or even missing passwords.

Although operations were temporarily disrupted, officials reported that drinking water supplies remained safe.

In a separate incident, the U.S. Justice Department accused an Iranian hacker of repeatedly gaining unauthorized access to the control system of a small dam in Rye, New York. According to prosecutors, the intrusion could have allowed the hacker to remotely operate the dam’s floodgate. However, the gate had already been taken offline for maintenance, preventing any physical harm.

Investigation Continues As Questions Remain

Authorities continue investigating who was ultimately responsible for the coordinated attacks on Minnesota’s water systems. While some officials believe Iranian-linked hackers may have played a role, investigators have not publicly identified a specific actor or announced any final conclusions.

The incident has renewed concerns about the security of America’s aging infrastructure and whether states are adequately prepared to defend essential public services from increasingly sophisticated cyber threats.

At the same time, Trump’s criticism has placed renewed attention on Gov. Tim Walz’s record, arguing that protecting critical infrastructure requires not only strong cybersecurity but also effective leadership and government accountability. As the investigation moves forward, both the source of the cyberattack and Minnesota’s preparedness are likely to remain at the center of the national debate.
