I seem to recall someone stating he has yet to activate the National Guard and place them down south through known points of entry. I could be mistaken and will definitely recant if he has. He seems to me a guy seeking a microphone with less than needed action when it comes to this
I believe a Governor has very limited ability to activate the National Guard.
I also have heard that Perry has called up the Guard to the extent he is allowed. The National Guard requires POTUS calling up. Maybe this is due to costs, don’t know, but he said Texas alone has spent $5 billion on Border security which is the Constitutional responsibility of the Federal Government.
