President Donald Trump dismissed the possibility that Iran was behind recent cyberattacks on Minnesota water systems, instead blaming the state and its Democratic governor, Tim Walz, without providing evidence. The comments matter because investigators have not yet publicly identified those responsible, while federal agencies have warned of an ongoing threat to critical infrastructure from Iran-affiliated hackers.

More than 30 Minnesota water systems were targeted over Sunday and Monday, though officials reported no harm to residents; one town briefly asked people to conserve water. The FBI is investigating, and government agencies had issued an advisory the previous week about Iranian hackers targeting water and wastewater systems, although Iran’s involvement in the Minnesota incidents has not been confirmed.
