There's a story in the New York Times about President Obama's love of books and reading. I doubt that Trump has ever read a book in his life. Not even the ones he's meant to have written!
Apparently he kept a copy of 'My New Order', a collection of Hitler's speeches, by his bed. His ex-wife mentioned it, and he confirmed it in an interview, although he thought it was Mein Kampf.
His ghostwriter doesn't think he read it though, as he agrees with you - "I seriously doubt that Trump has ever read a book straight through in his adult life."
