In a 40 minute interview broadcast by NBC on Wednesday 28 June, Edward Snowden was asked about his career history, his life in Russia, the NSA’s capabilities and the possibilty of him ever returning to the United States. During the broadcast, Edward Snowden described making his concerns about surveillance practices known both formally and informally before going public – something that NBC was able to confirm during the broadcast was indeed the case.
Three further short clips from this interview were later released by NBC.
