The wall has been evolving. It began as a big beautiful wall quite possibly with solar panels along the top, paid for by Mexico along the entire border. Republicans never challenged Trump much on that as they knew they could deal with the nonsense later. If, and that’s a pretty hefty if, it makes its way into the DACA bill, it will not be paid for by Mexico, but by those Americans that actually pay taxes, much of it already exists via the rivers and mountains along our border, snicker snicker, and it may come in the form of fencing, and added security measures having nothing to do with physical/tangible barrier. Yawn.
