NASA Administrator Bill Nelson has called for an investigation into reports that Elon Musk has been in regular contact with Russian President Vladimir Putin since late 2022, raising national security concerns. The Wall Street Journal reported that their discussions included personal topics, business, and geopolitical tensions, which could potentially give Musk access to sensitive government information due to his ties with NASA and the U.S. military. White House officials were reportedly unaware of these interactions, which have been described as a closely held secret within the government. One notable request from Putin involved asking Musk not to activate his Starlink internet service over Taiwan, allegedly as a favor to Chinese President Xi Jinping. Nelson emphasized the need for an investigation, stating that multiple conversations between Musk and Putin would be particularly concerning for national security. Musk has not commented on the allegations, while Kremlin officials claim they have only had one brief conversation.
