Very true. There are other good reasons for pre-arranging calls from a POTUS. It might be too shocking to get a cold call from a POTUS and the recipient might go 'deer-in-the-headlights' or get hysterical (think Publisher's Clearing House winner) or simply not believe it is the POTUS and hang up. It also gives the recipient time to get other grieving family members together as they might appreciate being present as well.
You guys are right. The call was probably pre-arranged.
Which, is why Rep. Wilson’s crap is all the more irritating. She planned to be there, and take advantage of it if possible. Whether that was the intent of the family is unclear.
