Any book or research on Donald Trump's branding and strategy?

I don't know how but I became obsessed with learning about Donald Trump in academic point of view in business (marketing/branding and strategy). With theme of "Success", he connects imagery of tall building with clothing, entertainment, vodka, and so on. I think his branding strategy is extremely interesting. You don't have to agree with me and it is premature to say this yet but I see some parallel between Trump brand and Jordan brand in its infancy.

Trying to find case studies or books on Donald Trump's branding and strategies, I searched sources such as Harvard Publishing and Standord Business Review etc.. Unsurprisingly, out of about hundreds of case studies about Donald Trump approximately 90%~95% of them are about politics or some criticism about his leadership.
I am actually a little confused why there isn't any searchable case studies about his business on Harvard Business Review.

I find one book on Amazon "Trump Business: The Business Empire of Donald Trump". However it does not go deep. Also, I did not think this book was objective enough.

Does anyone know 100% objective book or research about Donald Trump's branding and strategy?
