That they hired illegals doesn’t surprise me. The question that kept running through my mind was “Why would an illegal immigrant work on a fence designed to keep illegals out? What if they get caught?”
Maybe they infiltrated the workforce and where secretely building concealed passages on the wall; those tricksy immigrants with their sombreros and shifty eyes…
D.L. Hughely did a bit about this on Leno a while back. “They’re going to build a fence to keep the Mexicans out. Oh yeah? Who’s gonna build it? White people sure as hell aren’t going to build a fence out in the desert” etc.
