US sees Russian hand in envoy's bugged call

US officials have said they suspect Russia is behind the leak of an apparently bugged phone conversation about Ukraine between two senior American diplomats in which they make disparaging comments about the European Union. The officials noted that an aide to Russian deputy prime minister, Dmitry Rogozin, was among the first to tweet about a YouTube video that contains audio of the alleged call between the top US diplomat for Europe, Victoria Nuland, and the US ambassador to Ukraine, Geoffrey Pyatt.
