The U.S. government’s efforts to determine which highly classified materials Snowden took from the National Security Agency have been frustrated by Snowden’s sophisticated efforts to cover his digital trail by deleting or bypassing electronic logs, government officials tell the AP. Such logs would have showed what information Snowden viewed or downloaded. (AP Photo/The Guardian, File)
