On the last day of November, the New York Times ran a story headlined "White House Plans Tillerson Ouster From State Dept., to Be Replaced by Pompeo."
As recently as Monday, the Times reported, "a White House spokesman berated a reporter for suggesting there was any kind of split between Mr. Tillerson and the White House because of disparate comments on Russian responsibility for a poison attack in Britain."
That same month, Trump tweeted that he told Tillerson "that he is wasting his time trying to negotiate with Little Rocket Man ... Save your energy Rex, we'll do what has to be done!"
And Trump wanted to make a change before the North Korea summit.
Although the Post said John Kelly told him Friday that Trump wanted to make a change, Tillerson seemed unaware as he cut short his visit to Africa that the time had come.
