CISA Acting Head Uploads Sensitive Data to ChatGPT

Madhu Gottumukkala, the acting head of the United States — Cybersecurity and Infrastructure Security Agency, reportedly uploaded sensitive government contracting documents, marked 'For Official Use Only,' to the public version of ChatGPT in August 2025. This action triggered automated cybersecurity alerts within United States — Cybersecurity and Infrastructure Security Agency and prompted an internal review by the United States — United States Department of Homeland Security to assess potential data compromise. The use of ChatGPT by Madhu Gottumukkala was granted a temporary exception, despite most United States — United States Department of Homeland Security employees being blocked from the platform due to data security concerns. The incident, initially reported by Politico, has fueled scrutiny of Madhu Gottumukkala's leadership, including previous controversies such as an 'unsanctioned' counterintelligence polygraph and an attempt to remove Robert Costello, CISA CIO. The event has sparked broader discussions about the appropriate use of AI tools in government contexts where data security is paramount, especially given that information uploaded to OpenAI's ChatGPT may be used to improve responses for other users.
