'Dumb as a rock; lazy as hell': President Donald Trump on his former Secretary of State Rex Tillerson

President Donald Trump, never known for taking criticism lying down, responded to unkind words from his former secretary of state Rex Tillerson on Friday by calling Tillerson “dumb as a rock” and “lazy as hell.” President Trump, while lavished praise on Tillerson’s replacement while demeaning the man he chose as his first secretary of state said.

However, last year Trump apparently had a higher opinion of Tillerson’s abilities, calling him “our wonderful secretary of state” and declaring that “we work well together.”

The attack from President Trump comes after Tillerson, the former Exxon Mobil CEO, discussed his difficult tenure working for Trump at a rare public appearance in Houston on Thursday evening.

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.”

Tillerson also said Trump frequently asked him to do things that he had to explain were illegal or otherwise ill-advised. It was an extraordinary rebuke from a man Trump once said would be “a star!” at the State Department.
