There’s a whole lot of info in this article about Trump’s meltdown over Tillerson calling him a fucking moron, but I wanted to highlight this:

Pence was incensed upon learning from the NBC report that Tillerson’s top spokesman had said he once privately questioned the value of Nikki Haley, the U.S. ambassador to the United Nations. Officials said the spokesman, R.C. Hammond, fabricated an anecdote that Pence had asked Tillerson in a meeting whether Haley, who is seen as a possible successor if Tillerson, is helpful or harmful to the administration.
