National Security Agency implicated in spying row
One of America's leading journalists believes that he is being monitored by the US National Security Agency (NSA).
Brian Ross, chief investigative correspondent for ABC News, wrote in his blog that a senior source warned him that his phone calls were being monitored in an attempt to identify his sources.
Ross was one of a number of journalists who broke the story of CIA jails being set up in Eastern Europe.
"It's time for you to get some new cell phones, quick," the source warned in an in-person conversation.
