From National Review:

Sadly, there are some (including, apparently, the president of the United States) who compare and contrast the Lynch/Holder DOJ and the Sessions DOJ and conclude that Sessions is in the wrong, that he should be more loyal and “fight fire with fire.” This view is dangerously misguided. Writing Monday in USA Today, former Sessions staffer Cameron Smith and former Obama ethics czar Norman Eisen rightly laud Sessions and conclude with the key point: “When our personal viewpoints clash, the dispassionate enforcement of our laws steadies our republic.”
