You said it, it is an old building. If you are going to include new, more credible news providers, who are you going to exclude in order to make additional room? The second building is in close proximity to the WH. I would think that any communication issues should be able to be overcome by technology, and a forward thinking Communications Director. Maintaining the status quo is exactly what the legacy MSM wants, and that's what needs to change.
The first thing that needs to be done is break the "Press Association" (or whatever they call themselves.)
They also need to be moved out of the WH proper. They can be relocated to the office building next door, in a room large enough to allow for alternative media, such as RAV.
Seating in the room needs to accentuate alternative media. The legacy MSM can be seated in the back row. They don't like it, they can pound dirt. Let them continue to trash their way into irrelevance. I mean, they are basically there now.
Beyond time for the Pravda platoon to be put in their place.
and as brilliant as a night lite bulb.
