Graham gave Trump his number when he was begging for money. After calling Trump a jackass, the Donald decided to punk the weasel by giving out his number to his SC constituents. So Linda gets a new phone and this time it will be a smartphone something he had never owned before. Graham is not a big supporter of privacy when it comes to NSA collecting data.
What Trump did was not “punking th wesael” so to speak.
He played down to Graham.
I think it shows he has a thin skin.
