How can Fox News be labeled “destructive” and MSNBC considered “invaluable” by the White House?

That‘s the question CNN’s John King was asking last night during a segment in which he pitted the “destructive” network against the “invaluable” one. By showing clips of both Fox and MSNBC hosts, King mocked Obama’s recent comments that Fox is a “destructive” force while a White House spokesman said that MSNBC’s Keith Olbermann and Rachel Maddow provide “an invaluable service” to the country.
