Since there are logistics involved in moving the President, I think he moved fairly quickly. I am sure Krauthammer knows this as well.
I think you are right about an agenda. When I found out these people with Shep are from the Superdome that didn't want to go to the Astrodome, it meant he had to know the same thing and NEVER reported that fact.
Agenda from the media all the way around except the local media.
