I think the President should just ignore the judge.
It is the President, under the Constitution that has the responsibility to protect the country, and we are under a NED.
It is a clear separation of powers issue.
Like Andy Jackson said, “The judge has made his ruling, now let him enforce it.”
I agree completely. Jackson may have also said something along the lines of, regarding the jurist, “How many soldiers does he have?”
This was an agreement between United States and Mexico and I don’t see how a district judge can knock it down.
