From the June 26 edition of Fox News' MediaBuzz:
HOWARD KURTZ (HOST): CNN has hired a brand new political contributor, Corey Lewandowski, seemingly seconds after Donald Trump fired him as campaign manager. Well no knock on Corey, but this is a sad move by CNN because Lewandowski, who handled his dismissal with class, has made clear he doesn't plan to utter a negative syllable about his ex-boss.
Lewandowski insists he'll call balls and strikes as he sees them, but even if he wants to criticize Trump he really can't because he signed a non-disclosure agreement as Burnett pointed out promising not to demean or disparage Trump. Now lots of former operatives work for cable news channels these days but even leaving aside Lewandowski's rough relations with some reporters and the Michelle Fields grabbing incident, I just don't see where this helps CNN's credibility in covering Donald Trump.
