When many of us say “the wall”, we mean controlling access to the country. There is the physical, high tech wall, but there’s also control of access via coasts, seaports, airports, visas, and work permits. That implies a function e-verify system, even though it isn’t said every time, because this is a long paragraph. “The wall” is shorthand for “controlled access to the country”.
What I am saying is that if I was going to do one thing today, to stop this tide, it would be mandatory e-verify. You would have to expand the current system, but you could pull funding from the deferral spending and put it into the expanded system. The plus is that you don’t have to create a new system. It’s already there.
