The Washington Post reports the head of the U.S. intelligence community on Wednesday called on Edward Snowden, a former contractor with the National Security Agency, to return the massive trove of documents in his possession. Speaking before a Senate panel, James R. Clapper Jr., delivered blistering criticism of Snowden, describing him as a hypocrite who has severely harmed national security. Clapper said the materials exposed by Snowden have bolstered adversaries, caused allies to cut off cooperation with the United States, triggered changes in communications by terrorist networks and put lives of intelligence operatives and assets at risk. “Snowden claims that he has won and his mission is accomplished,” Clapper said. “If that is true,” he added, Snowden should return the documents that have not been released.
