Former White House official Omarosa Manigault Newman’s new book says her former colleague, Kellyanne Conway, is a fraud who only rooted for Trump after she left Sen. Ted Cruz’s team.

“I’d marveled at the speed with which Kellyanne’s allegiance changed during the campaign,” she wrote in “Unhinged: An Insider’s Account of the Trump White House.” “While working for the Cruz super PAC, she criticized Trump daily and called his integrity and character into question. And then, when she changed camps, she was gung-ho for him.”
