Apparently, he's designed an electrified fence that could be strung along the U.S.-Mexico border. In case we didn't get the idea, he actually built a prototype on the floor of the House, explaining as he did:
I also say we need to do a few other things on top of that wall, and one of them being to put a little bit of wire on top here to provide a disincentive for people to climb over the top or put a ladder there. We could also electrify this wire with the kind of current that would not kill somebody, but it would simply be a discouragement for them to be fooling around with it. We do that with livestock all the time."
He sees no irony here... no problem in thinking that we would treat people as we treat livestock. I guess this shouldn't surprise me from a man who thinks McCarthy was a great American hero and that illegal immigrants are responsible for the deaths of 25 Americans every day. I was expecting, perhaps, intellectual agility?
