Trump basically got most of his money for the wall in a roundabout way.

If he succeeds in getting a second term he will most likely finish building the wall. He will be halfway through by the election season. If he wins he most likely will finish building the wall.

The wall isn't even supposed to stop 100% of border crossers its to slow down any new people from entering. Make it harder to get across.

Even this pandemic, they are taking advantage to speed up construction.

Why give something when you don't have to?
