Nancy Grace's fight with a scientist over whether or not radiation in Japan would reach the U.S. also made the new segment. But Grace's "refusing to take science for an answer" was just a warm up for the main event: the feud between Fox News's Steve Harrigan and CNN's Nic Robertson (with a brief interruption by John Oliver in a wizard costume).
The fight started when Fox News insinuated that Robertson and other journalists were used as "human shields" by Libyans by going on a tour of Muammar Gaddafi's compound that had been the site of a missile attack. Fox also made a point of reporting that their own Steve Harrigan wouldn't be going to the site, but later said Harrigan had actually sent "a security guard with a camera" in his place so as not to lose coverage.
"[He] was so concerned that journalists would be used as human shields, he made security guard 'Joey Expendable' go. 'Hey Joey! You know how you always said you wanted to be a real, live reporter? Well how about just a reporter?'"
Nic Robertson fired back at Harrigan personally, to Stewart's delight. Watch the full clip to see Stewart break down their back-and-forth in something he calls "reporter snaps."
