"Credibility Vs. Transparency: A Closer Look at NPR and Its Ethics Code":

Two weeks ago, they drew criticism over a memo sent from the news department to staffers reminding them, among other things, that they were not allowed to attend Jon Stewart’s and Stephen Colbert’s upcoming rallies. Then, last week, they fired long-time news analyst Juan Williams after some remarks he made on Fox News’ The O’Reilly Factor. In both cases, the network came under fire for political bias and for stifling free speech.
