While Tillerson had reportedly called Trump a "moron" while part of the president's cabinet, he made his views unequivocally clear Thursday when he told the CBS' "This Morning" that Trump was "pretty undisciplined" and "doesn't like to read". He called the president "undisciplined" and said the president "doesn't like to read, doesn't read briefing reports, doesn't like to get into the details of a lot of things".
Trump voiced anger hours later in a harsh tweet, saying that Tillerson "didn't have the mental capacity needed" to be the top United States diplomat.
In it, he described what he perceived as a hard working relationship with President Trump.
The president made his comments in a Friday tweet. He said Tillerson "didn't have the mental capacity needed for the job" while praising Tillerson's replacement, Mike Pompeo. "And I think he grew exhausted of me being the guy every day that told him 'You can't do that, and let's talk about what we can do'".
Addressing a question on Trump's response to deadly riots at a white nationalist rally in Charlottesville, Virginia, last August, where he said there were "very fine people" on both sides, Tillerson threw shade by telling Fox News that "the president speaks for himself".
"When the president would say, 'Here's what I want to do and here's how I want to do it, ' I'd have to say to him, 'Mr".
But perhaps the biggest challenge for Tillerson, he says, was constantly being the person to tell Trump he couldn't do something. "It violates a treaty.' You know, he got really frustrated". "Now it is a whole new ballgame, great spirit at State". Even as he dismissed Tillerson's alleged insult as "fake news", he said at the time that if the diplomat "did that, I guess we'll have to compare IQ tests".
A billionaire from his time at the oil giant, Tillerson has been largely quiet since he was sacked by Trump in a tweet in March.
Tillerson, who reportedly called Trump a "moron" after a discussion with the president about the country's nuclear arsenal, was sacked in March and replaced with Mike Pompeo.
"I will be honest with you", he said, according to the Chronicle.
After the "moron" reports, Trump threw a public barb at his secretary of state.
