Yes,Ivanka is the one to calm daddy down,make sure his sleeping meds are taken, and be there to pull his phone away  when he starts foolish twittering.  She needs to be the first one there before he starts ranting in a high level meeting.  She needs to be there for the "3AM" CRISIS CALL.  She is the only one trumpf trust in his created "backstabbing" world. HE TRUST NO ONE EXCEPT ONE FROM HIS LOINS.  He's a lonely Rich old man that even his 3rd wife is estranged from. SAD.
