From an October 8 Time.com article:

The general in this war is [White House communications director Anita] Dunn, 51, a veteran campaign strategist who arrived at the White House in May. She has been a force in Democratic campaigns since the late 1980s and helmed Obama's rapid-response operation during his run. At the White House, she has become a devoted consumer of conservative-media reports and a fierce critic of Fox News, leading the Administration's effort to block officials, including Obama, from appearing on the network. “It's opinion journalism masquerading as news,” Dunn says. “They are boosting their audience. But that doesn't mean we are going to sit back.” Fox News's head of news, Michael Clemente, counters that the White House criticism unfairly conflates the network's reporters and its pundits, like Glenn Beck, whom he likens to “the op-ed page of a newspaper.”
