Can’t close without wall
Closing ports puts political pressure. It also frees up more CBP to deal with the “asylum seeker” mess all along the border.
I am very aware can’t close the whole border without a wall thank you. I live in the New Mexico bootheel where our border fence is a wire cattle fence only. I have illegals come to my home, watch high speed chases with smugglers- all that fun that goes with that. I have been dealing with border issues many years.
We need a wall, we also need Congress to change our asylum laws, and if Mexico allows illegals to enter to come here, they need to be stuck with them.
