Guardian journalist Glenn Greenwald took Meet The Press host David Gregory head on in an interview Sunday morning, after Gregory asked if Greenwald would be criminally culpable for "aiding and abetting" NSA leaker Edward Snowden.
"I think it's pretty extraordinary that anybody who would call themselves a journalist would publicly muse about whether or not other journalists should be charged with felonies," Greenwald said. "The assumptions in your question, David, is completely without evidence, the idea I've aided and abetted him in any way. The scandal that arose in Washington before our stories began was about the fact that the Obama administration is trying to criminalize investigative journalism by going through the e-mails and records of AP reporters, accusing a Fox News journalist of the theory you just embraced, being co-conspirator in felonies for working with sources."
"If you want to embrace that theory," Greenwald continued, "it means that every investigative journalist in the United States who works with their sources, who receives classified information, is a criminal. It's precisely those theories and precisely that climate that has become so menacing in the United States. It's why the New Yorker's Jane Mayer said investigative reporting has come to a standstill, as a result of the questions you just mentioned."
Gregory was very unhappy at being personally implicated in Greenwald's answer. "The question of who's a journalist may be up for debate, in regards to what you're doing" Gregory said. "Anybody who's watching this understands that I was asking a question. That question has been raised by lawmakers, as well. I'm not embracing anything. But obviously I take your point."
