Purported Deepfake Audio Allegedly Impersonates U.S. Secretary of State Marco Rubio in Starlink Disinformation Campaign

A purported deepfake audio clip allegedly impersonating U.S. Secretary of State Marco Rubio falsely claimed he vowed to pressure Elon Musk into cutting Ukraine’s access to Starlink. The reported clip was inserted into a purportedly manipulated CNN interview. It was then reported to have spread across multiple languages and fueled disinformation about U.S.-Ukraine relations. Forensic analysis reportedly confirmed the audio was AI-generated.
