Trump doesn't turn on people. Loyalty has always been everything with him.
It's kind of muddled. He feels personally loyal to people like Flynn, Lewandowski, etc. but not professionally loyal; it's not loyalty that comes up with unimpeachable (heh) job security. Lewandowski was fired, Manafort was fired, Flynn was fired, and so on.
That said, it's hard for me to think Trump will turn on Kushner in any way, personally or professionally, given that he is his son-in-law.
Probably aggregating all of his social media followers, not just Twitter bots, but I don't really want to look him up on Facebook or Instagram to confirm it.
