“President Biden has instructed his agencies to ignore federal statutes that mandate the detention of illegal immigrants. 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.”
In fact a lot of Texas' economy relies on access to the US dollar, of which they would absolutely lose access to if there was even the hint of leaving.So that’s not how it works. The USD is the official currency in more than just the USA, just like the Euro is an official currency in countries outside of Europe. If it’s the currency people trade in then it makes its way inside the territory, no country can prevent their money from being used elsewhere.
