Here's a paste from page 302, which I think is in the final chapter.
"By October, however, many on the presidents staff took particular notice of
one of the few remaining Trump opportunists: Nikki Haley, the UN ambassador.
Haleyas ambitious as Lucifer, in the characterization of one member of the
senior staffhad concluded that Trumps tenure would last, at best, a single
term, and that she, with requisite submission, could be his heir apparent. Haley
had courted and befriended Ivanka, and Ivanka had brought her into the family
circle, where she had become a particular focus of Trumps attention, and he of
hers. Haley, as had become increasingly evident to the wider foreign policy and
national security team, was the familys pick for secretary of state after Rex
Tillersons inevitable resignation. (Likewise, in this shuffle, Dina Powell would
replace Haley at the UN.)
The president had been spending a notable amount of private time with Haley
on Air Force One and was seen to be grooming her for a national political future.
Haley, who was much more of a traditional Republican, one with a pronounced
moderate streaka type increasingly known as a Jarvanka Republicanwas,
evident to many, being mentored in Trumpian ways. The danger here, offered
one senior Trumper, is that she is so much smarter than him.
