Funny, I just saw Newt on Fox about 10 minutes ago.
I would be Trump won’t be VP or Chief of Staff. The latter is basically an appointment secretary, a job for a younger man. I don’t see him an administrator either. My bet is some kind of senior presidential advisor, like Valerie Jerrett.
I have wondered if his son, Erick Trump, is the one that will take that job. He seems to be doing something like that for Dad on the campaign trail.
