The Pentagon refused to investigate starlink restrictions in Ukraine, which made it difficult to intercept Russian drones, -. AP. A bipartisan group of nine US senators - four Republicans and five Democrats - has demanded that the Pentagon's inspector general investigate the disruptions to Starlink and the military's Star Shield system. However, he said that these issues should be addressed by the US Air Force. The Air Force, in turn, did not respond to either the journalists' request or the senators' request.
