No idea. I noticed his numerous rants, in particular the one about fentanyl and how a large quantity was seized at an airport, so a border wall would be stupid. Almost like if forced to go thru a official checkpoint these dangerous drugs get caught. Imagine that.
Estimate is that over 80% of illegal drugs are muled around checkpoints as well as that is exactly what the illegal invaders do.
Bail out of vehicles prior to checkpoint, are picked up by coyote in brush across fence and then guided around checkpoint to another pickup.
