A piece in the WSJ today announces that Trump may be considering an advisory role for Elon Musk. This would be the first time in my memory that a president has brought on someone with actual knowledge of a topic to advise him.
Rumor has it he's also courting Vivek Ramaswami, who at this point is not terribly enthusiastic about joining the Trump team.
While he's at it, he might consider Christie Noem in a position relating to down sizing the government. This should work well and prove to be a fairly smooth operation as many government employees would take the hint and either resign or take early retirement.
