The Pentagon refused to investigate the Starlink outages in Ukraine. Senators demand investigation into Musk's role Nine US senators - four Republicans and five Democrats - have demanded an investigation into who is behind the restrictions on Starlink satellite communications and Star Shield that Ukrainian officials say prevented Russian drones from being intercepted. But the Pentagon's inspector general declined to investigate and suggested contacting the US Air Force, the Associated Press reports. The senators wanted to find out whether US officials approved the communications restrictions, knew about them in advance and how they affected Ukrainian air defenses and threat warnings. Senator Jeanne Shaheen said the Trump administration and SpaceX are giving conflicting explanations for what happened, so an independent investigation is needed.
