Condemning the Fox News Channel as a warmonger that is agitated for a US attack on Iran, documentary filmmaker Robert Greenwald and US Senator Bernie Sanders announced an "online viral video campaign" Wednesday calling on television news organizations "not to follow Fox down the road to war again." Greenwald, the director behind "Outfoxed: Rupert Murdoch's War on Journalism" and "Wal-Mart: The High Cost of Low Price," has compiled a new three-minute video that mashes clips from Fox's coverage of the 2003 invasion of Iraq and its aftermath with recent coverage of possible US military action against Iran. The video and an accompanying "open letter" to ABC, NBC, CBS, MSNBC and CNN urge news organizations to ask tough questions about administration policy on Iran and say citizens should pressure them to do so. One media observer said the video lacked balance and journalistic credibility. "They are accusing others of doing what they have done, which is to stitch together multiple snippets of video and very short sound bites to make an ideological argument," said Bob Steele, the Nelson Poynter Scholar for Journalism Values at the Poynter Institute school for journalists in St. Petersburg, Florida.
