Nikki Haley, former U.S. ambassador to the United Nations under President Trump, revealed this week that two former senior administration officials worked to undermine the president when she was the ambassador. Those officials were Secretary of State Rex Tillerson and Chief of Staff John Kelly. Haley describes in her new book how the two former officials tried to sway her toward subverting the president. This example isn’t an outlier. The type of subversion explained by Haley has occurred countless times against President Trump.
