President Donald Trump has claimed, without presenting evidence, that Minnesota's government was responsible for a cyberattack on the state's water systems, contradicting U.S. officials who suspect Iran.

At a July 31 Cabinet meeting, Trump stated, "I don't think so. I think I blame it on Minnesota because they're grossly incompetent." He specifically targeted Minnesota Gov. Tim Walz, accusing him of corruption. This assertion diverges from a New York Times report indicating that investigators believe Iranian hackers likely orchestrated the attack on over 30 municipal water systems.

Gov. Walz responded, "Trump knows exactly who is responsible for this attack, and knows that other states were hit too." He criticized the Trump administration for weakening cybersecurity agencies, leaving the U.S. exposed. The cyberattacks, which occurred on July 26 and 27, affected operational technology in Minnesota's water utilities, prompting boil-water notices in some areas. Investigations are ongoing, and no specific actor has been definitively identified by the state. U.S. cybersecurity agencies are involved in the investigation. Iranian-linked hackers have a history of targeting U.S. water systems, with advisories issued by the EPA and CISA warning of such threats.
