Trump 'undisciplined', says Tillerson

Speaking at an event in Houston, Texas, Tillerson said, “What was challenging for me coming from the disciplined, highly process-oriented Exxon Mobil corporation, was to go to work for a man who is pretty undisciplined, doesn’t like to read, doesn’t read briefing reports, doesn’t like to get into the details of a lot of things, but rather just kind of says, ‘This is what I believe’.”

After Tillerson's surprise pick as secretary of state, things didn't work out well between him and Trump. He had once reportedly called Trump a “moron” and never expressly denied it. Trump fired him in March.

“So often, the president would say, ‘Here’s what I want to do, and here’s how I want to do it,’ “ Tillerson said, according to the Houston Chronicle, “and I would have to say to him, ‘Mr. President, I understand what you want to do, but you can’t do it that way. It violates the law’.”
