Both Eric and JR were with Trump when he went to Pence’s for breakfast, but only Eric joined the family for dinner at the Capital Grill in downtown Indy last night Did Jr fly in with the jet this morning? Can’t imagine Donald missing a meal.
Now, I take all that with a grain of salt, but if that's the dynamic, I think it's Pence.
Trump trusts Ivanka, Jared, Jr, and Eric perhaps more than he trusts his instincts.
Besides, Christie not being AG would be a complete waste of talent and resource. I don't think Trump could look past that.
