“[Donald Trump] is jealous of everyone’s height,” Wolff said.
“He never lets himself be in a photograph with someone taller than he is.
Height is one of his techniques.

Donald Trump is certainly tall compared to most people, but hisson Barron has grown even taller.

He’s too cool, the kids.”
Karl called the moment “surreal” while speaking to CNN (viaFacebook).

Michael Wolff’s recounting of the contentious Trump family dynamics offers a plausible cause for Barron’s hesitancy.
