The interim chief of the country’s cyber defense agency reportedly uploaded sensitive government records into a publicly accessible artificial intelligence platform last summer. Senior DHS leadership initiated an internal assessment to determine whether the exposure posed any risk to government operations. The review involved then-acting General Counsel Joseph Mazzara and DHS Chief Information Officer Antoine McCord, officials said. Gottumukkala later held discussions with CISA Chief Information Officer Robert Costello and Chief Counsel Spencer Fisher regarding the handling of restricted documents. The administration’s nominee to permanently lead the agency, DHS adviser Sean Plankey, remains in limbo after his confirmation stalled last year following objections from Republican Sen. Rick Scott of Florida tied to an unrelated contracting dispute.
