I am sure that is being worked on right now.
Maybe they are waiting for closer to Election Day.
We’ll see.
I suspect Mr. T already knows many of the people he wants in his cabinet and as advisors, etc. and probably has staff vetting them. As I’ve said before, I’d like to see Stephen Miller as Press Secretary (with Diamond and Silk filling in now and then :-)
I remember reading a discussion on FR a while back about this very thing - Trump announcing his Cabinet early. Someone had what I thought was a good point - if he announces early, it gives the media and Clinton a lot of time before the election to take each of the proposed Cabinet members apart (and you know they will) (paraphrasing what that FReeper said). Plus, if he announced prior to the election, would some (especially media) call him presumptuous - think Cruz announcing Carly as VP.
