Trump had an answer to this in his speech on immigration last week.
Trump said the border will be patrolled above at and under ground.
Journalist can’t report objectively. I know it’s all too obvious.
Trump’s words about the wall in his immigration speech:
“On day one, we will begin working on an impenetrable physical wall on the southern border. We will use the best technology, including above-and below-ground sensors, towers, aerial surveillance and manpower to supplement the wall, find and dislocate tunnels, and keep out the criminal cartels, and Mexico will pay for the wall.”
