US Homeland Security Secretary Mullin said the incident under scrutiny has no connection to Microsoft, according to a First Squawk tweet. The statement rules out Microsoft as the source of the event, though the tweet did not specify what the incident was or which systems or parties were involved. The remark matters because it narrows where responsibility and potential financial exposure may fall, sparing Microsoft from being tied to the disruption. What to watch next is further detail on the incident itself, including its cause and scope, and any follow-up comments from DHS or Microsoft.
