The Guardian's Glenn Greenwald appeared on ABC's "This Week" on Sunday and told host George Stephanopoulos that the public should expect more revelations from him.
Last week, Greenwald broke the bombshell story about the NSA collecting phone data from millions of Verizon customers. Additional stories on major government surveillance programs followed, including news about the NSA program called Prism that allows officials to collect material from some of the country's largest Internet companies (including AOL, HuffPost's parent company). On Sunday, Greenwald published another story about an NSA datamining tool used for global surveillance called Boundless Informant.
"Should we be expecting more revelations from you?" Stephanopoulos asked Greenwald.
"You should," he said.
During the segment, Greenwald responded to criticisms from the Director of National Intelligence, James Clapper, who called The Guardian's reports "reprehensible." Greenwald said:
Every single time any major media outlet reports on something that the government is hiding, that political officials don't want people to know, such as the fact that they are collecting the phone records of all Americans, regardless of any suspicion of wrongdoing, the people in power do exactly the same thing. They attack the media as the messenger and they are trying to discredit the story. This has been going back decades, ever since the Pentagon papers were released by the New York Times, and political officials said you are endangering national security. The only thing we've endangered is the reputation of the people in power who are building this massive spying apparatus about any accountability who are trying to hide from the American people what it is that they are doing.
Last week, NBC justice correspondent Pete Williams said that it was "very likely" the Justice Department would investigate the leak. Greenwald told The New York Times that his source was "a reader" of his. On "This Week," Greenwald said that there could have been more than one source. "Have you been contacted by the FBI or any law enforcement official yet?" Stephanopoulos asked.
"No. And any time they would like to speak to me, I would be more than happy to speak to them, and I will tell them that there is this thing called the Constitution, and the very first amendment of which guarantees a free press," Greenwald said. "As an American citizen, I have every right and even the obligation as a journalist to tell my fellow citizens and our readers what it is that the government is doing, that they don't want people in the United States to know about, and I'm happy to talk to them at any time, and the attempt to intimidate journalists and sources with these constant threats of investigation aren't going to work."
