Minnesota Gov. Tim Walz forcefully rejected an unfounded claim from President Donald Trump that Minnesota was behind recent cyberattacks on municipal water systems. Walz’s response on Friday pushed back on the allegation and portrayed it as baseless.

The dispute centers on cyber incidents involving local water infrastructure, an area that has drawn heightened concern because of the potential risks to public services. Based on the available report, Trump publicly tied Minnesota to those attacks, while Walz answered with a sharp denial.

Walz’s reaction places the issue at the intersection of politics and cybersecurity. Rather than focusing only on the broader threat to municipal systems, the exchange turned into a direct confrontation over responsibility for the attacks and the evidence behind the accusation.

The brief account does not include further detail about the specific attacks or any proof supporting Trump’s statement. What is clear is that Walz used his response to reject the claim outright and defend Minnesota against the president’s allegation.
