Would it surprise you to learn the wall is already being built? :)
Our Potus is a sly one. He is not going to build those concrete prototype walls that everyone is making such a big deal about, LOL. DHS said they wanted see thru walls for safety. So they are building 30' high bollard walls.
Thomas Wictor listed 5 sauces on a thread. I posted them here last night. I'm not going back to re-research it. You can look up Thomas or search back breads.
Potus never intended to use those concrete walls. They are a distraction. He also signed EO to clear the way for building permits.
Stable Genius.
