Elon Musk's Department of Government Efficiency has raised concerns among intelligence officials after posting details about the National Reconnaissance Office on its new website. A Trump administration official dismissed the concerns, citing publicly available data. Former intelligence officials warned that sharing workforce details could endanger personnel and aid foreign adversaries. A former CIA official called the disclosure a "significant" breach, while national security analyst Mick Mulroy emphasized the risks of exposing intelligence community investments and identities.
