Here's a thought: The Capitol Building grounds are where POTUS will show the world the mountain of election fraud evidence. This will go on for many hours/days. The fence and NG is to prevent any disruption in the broadcast. The newly built viewing structure will be used by the networks (all of which were identified previously in news reports) to set up their cameras and talking heads to "Show the World." The 'Giant Voice' is already installed and tested; the Big Screen that will display the evidence just hasn't been installed yet.
Same here anon. Interestingly, this approach works much better with friends than with family, in anon's experience.
