See The Paul Ryan Interview NBC Refused to Air

The NBC Nightly News refused to air an interview between Brian Williams and Paul Ryan in which Ryan defended himself against the "fact checkers".

So are they biased or what?

From IJ Review:

To be perfectly honest, the interview does look pretty bad for the Democrats and their mainstream media allies, given that Ryan is quicker on his feet than the political hit men being sent to take him out. But the Romney campaign knew about the interview, so there was a fair chance that the footage would see the light of day.

So now there’s not just the interview that went horribly awry for the Democrats, but the lingering question: what are you so afraid of, NBC?
