It was only announced that Trump plans to appoint him as communications director. While I understand the value of being "pro-active" and getting a running start, I know grasp the importance at time of being circumspect and not making a national idiot of yourself before your prospective boss has a chance to reconsider.
I'm not suggesting that Trump will pull back his appointment. He may love how blustery Scaramucci is, for all I know. After all, he's surrounded himself with belligerent lawyers who go around telling off others and attempting to bully them. (And how well has that been working out in the White House...) But if you've already got the got the job, there's no need to keep trying to convince the guy in charge to hire you. You can't get "more hired," the only other way to go through the door is out. So, why risk it?
Thank goodness the job has nothing to do with knowing how and when to communicate well...
