Speaking truth to power

An exchange between CNN’s Campbell Brown and White House spokesperson Valerie Jarrett:

Brown: So do you think FOX News is biased?
Jarrett: Well, of course they're biased. Of course they are.
Brown: OK. Then do you also think that MSNBC is biased?
Jarrett: Well, you know what? This is the thing. I don't want to–actually, I don't want to just generalize all FOX is biased or that another station is biased. I think what we want to do is look at it on a case-by-case basis. And when we see a pattern of distortion, we're going to be honest about that pattern of distortion.
Brown: But you only see that at FOX News? That's all that–you have spoken out about FOX News.
Jarrett: That's actually not true. I think that what the administration has said very clearly is that we're going to speak truth to power.

Don’t the people in the White House know that THEY are the ones in power? That their crusade against their critics at Fox is trying to SILENCE people speaking truth to power?
