I vaguely remember that but I couldn’t tell you who it was or when it was posted. Was around the time the NG was ordered to the border.
I seem to remember it was a law passed quite a while ago that set aside one or two hundred yards along the border as Federalized.
I thought at the time it would be funny if the Governor of California objected to troops along the border, and then found out that one or two hundred yards didn’t belong to California or private property owners, but is Federal Land, and troops could be stationed there.
At that point by Executive Order the strip from California to Texas could be designated a military base and armed soldiers could be stationed to defend the border.
