Investigators are intensifying a probe into a reported security leak involving a Qatar jet, according to multiple reports. The matter came into public view after The New York Times reported that the U.S. Department of Justice issued subpoenas to four New York Times journalists connected to coverage about concerns over the aircraft’s security. The reporting also describes efforts to obtain digital materials related to the journalists’ reporting, including requests involving phones held by U.S. officials or journalists. The investigation is framed around how information about the aircraft’s security was obtained and disseminated. The subpoenas reflect the U.S. government’s attempt to identify sources and trace communications connected to the reporting. The outlets do not indicate that any one individual has been charged, and the reports focus on procedural steps taken by prosecutors and investigators, including document and device requests. The situation highlights an ongoing legal dispute over access to journalists’ records and the effort to determine the origin of leaked or sensitive information tied to the Qatar jet’s security.
