Governor Greg Abbott is not messing around. He has just declared an invasion at the border using the constitutional authority given to the states in Article I and has invoked the right of the state to defend itself.
He writes that this constitutional authority “is the supreme law of the land and supersedes any federal statutes to the contrary.”
Here’s the declaration:
The failure of the Biden Administration to fulfill the duties imposed by Article IV, § 4 has triggered Article I, § 10, Clause 3, which reserves to this State the right of self-defense. For these reasons, I have already declared an invasion under Article I, § 10, Clause 3 to invoke Texas’s constitutional authority to defend and protect itself. That authority is the supreme law of the land and supersedes any federal statutes to the contrary. The Texas National Guard, the Texas Department of Public Safety, and other Texas personnel are acting on that authority, as well as state law, to secure the Texas border.
This is the entire declaration which can be found on the governor’s website:
