"Trump cited Newt Gingrich as the authority"

Gingrich is an authority on two subjects: himself and his very own up front and center narcissism. JHC, the self-titled genius assistant professor couldn't even get tenure at then backwater West Georgia College (now a "University"). As a result of that ignominious failure, Newt decided to enter an easier line of work - politics. Cheap, dirty, and corrupt. Yup, good old Newt found his destiny on that proverbial highway to Hell. And the sooner he checks into the hotel, the better for us all.

Disclaimer, I didn't get tenure either on my first try at Georgia State U in Atlanta. But I never boastfully declared myself a genius [I am not] with nary a blush.
