McMaster and the Commander

Policy brawls are routine in any White House, and Lt. Gen. McMaster can surely handle his corner. The issue for Mr. Kelly—and Mr. Trump—is what to do when disagreement inside the White House turns into vilification of his staff from the outside.

 .. Mr. Trump issued a statement of support for Lt. Gen. McMaster late on Friday, which in a better White House would settle the matter. But rather than question the general’s loyalties, perhaps Mr. Kelly should question Mr. Bannon’s. The former Breitbart publisher has been a White House survivor, but his warring habits have also been responsible for much of the White House dysfunction.

Mr. Trump may worry about the damage Mr. Bannon and his allies could do to his Administration if he is no longer part of the White House team. But if his minions continue to vilify his colleagues inside the White House, how can anyone tell the difference?
