What kind of expertise could Bannon offer that is not already there? He is simply an extension of Trump, which means the president feels he needs to babysit the NSC. It seems to me he does not trust the council to advise him properly unless he has a representative there to coach them. That is a profound lack of respect for our highest ranked civil servants and a disturbing indication that he seems to think they need a party representative to supervise them. Bannon should not be there.
