Tillerson was "exhausting" and imperious, and Kelly was suspicious of her access to the president, Haley, a former SC governor who quit the Trump administration a year ago, wrote in "With All Due Respect", due to be published Tuesday.
According to the Washington Post, Haley writes in "With All Due Respect" that Tillerson and Kelly confided in her that Trump was unsuited for the office of the presidency and they were resisting his directives in the best interests of the country. "The president didn't know what he was doing", she continued.
In earlier remarks on the program, Haley called impeachment the "death penalty" for the president and said that she did not see any reason to move forward with the move to impeach him.
President Donald Trump's former United Nations ambassador, Nikki Haley, alleges in her upcoming memoir that two administration officials who were ultimately pushed out by Trump once tried to get her to join them in opposing some of his policies.
Kelly and Tillerson were opposed to the move, while Haley had the support of Trump's son-in-law Jared Kushner.
Haley said she supported most of Mr Trump's foreign policy decisions that others in the White House tried to block or slow down, according to the Post.
Kelly told the paper that that if giving Trump "the best and most open, legal and ethical staffing advice from across the [government] so he could make an informed decision is 'working against Trump, ' then guilty as charged".
Haley, a former SC governor of Indian descent, left the United Nations job at the end of 2018 on good terms with Trump.
"It should've been, 'Go tell the president what your differences are, and quit if you don't like what he's doing.' But to undermine a president is really a very unsafe thing". And it goes against the Constitution, and it goes against what the American people want.
Haley's account could do a lot to keep her in the president's good graces-or at the very least keep her from becoming reviled by his base should she in fact run for president later. The two former officials couldn't immediately be reached for comment about the articles. The two top Trump aides disagreed and argued that doing so could result in greater threats to Israel.
"A leader's words matter in these situations".
Lt. Col. Alexander Vindman, for example, admitted that he did not know if anything Trump said to the president of Ukraine on their now-infamous phone call was illegal, but that he was concerned that Trump's views went outside the "interagency" consensus and reflected an "unproductive narrative".
The daughter of Indian immigrants also didn't agree with Trump's tweets against members of the liberal freshmen "squad" to "go back and help fix the totally broken and crime infested places from which they came".
Speaking with CBS News' Norah O'Donnell, Haley backed up Trump's attacks on Reps.
Haley's book comes out Tuesday.
