After Rex Tillerson Savaged Donald Trump in an Interview, Trump Just Fired Back on Twitter in the Most Juvenile Way

President Donald Trump on Friday lashed out at former Secretary of State Rex Tillerson after Tillerson savaged Trump in an interview with Bob Schieffer Thursday night.

Tillerson on Thursday shared some harsh words about Trump in an interview at the MD Anderson Cancer Center.

Asked by Bob Schieffer what he thought about his former boss, Tillerson began by reminding the audience that he had never met Trump prior to becoming the nation’s top diplomat.

Trump “acts on his instincts, in some respects it looks like impulsiveness,” said Tillerson. “But,” he added of the president, “it’s not his intent to act on impulse.”

He went on to describe Trump as:

"...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, ‘Look, this is what I believe, and you can try to convince me otherwise, but most of the time you’re not going to do that.’”

So, of course, Trump couldn't let it go, and in a fiery tweet went after Tillerson with schoolyard taunts and ad hominem attacks:

"Mike Pompeo is doing a great job, I am very proud of him," Trump boasted. "His predecessor, Rex Tillerson, didn’t have the mental capacity needed. He was dumb as a rock and I couldn’t get rid of him fast enough. He was lazy as hell. Now it is a whole new ballgame, great spirit at State!"

Twitter was quick to remind the president - who gloated during the campaign about hiring "the best people" - that he was the one who chose Tillerson.

And many couldn't believe this was the president of the United States speaking.

Tillerson, the former CEO of Exxon, runs circles around Trump.

He should take some advice from his wife's anti-bullying initiative.
