This may be a silly question for somebody who knows the answer... Why not make the border wall a Military Project? I mean is 15billion really worth shutting down the Government? Facts do differ depending on where you look. Though Apparrently F-22 fighter jets cost about 6 billion a piece. The US supposedly has more than 187 of these in service. So for the price of 3 Jets the entire wall could be built. So I say make it a Military project.
