On Monday night, sources close to Donald Trump promised that he hadn’t finished his feud with Tennessee Sen. Bob Corker. They weren’t kidding!

“The Failing @nytimes set Liddle’ Bob Corker up by recording his conversation,” Trump tweeted Tuesday morning. “Was made to sound a fool, and that’s what I am dealing with!”

Corker is relatively short in stature — he’s 5’7″ — while Trump is right around 6’3″. Corker’s height was, according to the Daily Caller, one of the big reasons the Tennessee Republican didn’t make the cut to be Trump’s secretary of state.

“Two sources with knowledge of the transition say that the Tennessee senator’s short stature was a key factor,” the Daily Caller report said. Yes, really.

The focus on Corker’s height is the latest example of the fact that the President of the United States name-calls like your average fifth-grade bully. As he demonstrated throughout the 2016 campaign, this is Trump’s default approach to politics — and life. He has a unique gift to zero in on people’s weaknesses and then pick at them relentlessly.
