I believe I know why. He lusts after her and thinks about her day and n ight 24/7 and WANTS her but he can't have her so he keeps trying to get her attention in any way that he can. I mean a guy who eats cheeseburgers in bed at 6:30 pm and tweets the contents of his mind to billions of complete strangers is to be pitied because clearly what is driving him is UNREQUITED LOVE! She will never belong to him no matter what he says or does or how much taxpayer money he demands be spent on things to investigate her. Keep her in the news so he can see her and hear her because he is so lost without his Hillary fix. Even a prez can be pitied and he is surely an abjectly supremely a pitiful man.
