Glenn Greenwald, who recently announced his departure from the Guardian, told conference of reporters on Monday that he had more stories to come based on the leaked documents from NSA whistleblower Edward Snowden. Those stories, he said, would include examples of the U.S. spying on American citizens. Greenwald spoke by video to the Inter American Press Association, and asked his colleagues there to work together against a "sustained attack" on press freedom in the Americas. Greenwald, an American, is based in Brazil. 

Greenwald's latest Snowden story was published earlier on Monday in Le Monde, starting something of a war of words between France and the U.S. The story revealed that Americans have collected data from over 70 million telephone calls made in France during one 30-day period. France summoned the U.S. ambassador on Monday over those claims, even though France pretty much does the same sort of surveillance on its own citizens. The story comes one day after a different batch of Snowden reporting, this time in Der Spiegel, revealed that the U.S. had hacked into the email account of the president of Mexico. 

According to the AP, Greenwald also outlined the process he goes through to determine which documents get reported out: 

He's committed to reporting on every document of public interest given to him by former NSA contractor Edward Snowden. He said he does consider the potential harm that could be caused by his disclosures and consults with experienced editors and reporters in deciding what to publish. He also said they present their reporting to the government at issue to listen to officials' view about publishing the information, but he acknowledged they usually disregard it. "I don't think anyone could say we have not been thoughtful enough," he said. 

Snowden recently told the New York Times that Greenwald, along with a handful of other journalists, are the only people (aside from the NSA) in possession of the documents he leaked. The whistleblower faces espionage charges for his role in the much-discussed stories outlining the extent of U.S. surveillance around the world and at home. 

Greenwald will leave the Guardian, where he's done the bulk of his reporting on the NSA's secrets, for a new venture funded by eBay founder (and Greenwald fan) Pierre Omidyar.
