The formal, official groundwork is now laid for actual Civil War inside the United States. The Governor of Texas has declared, in writing, that the federal government has "broken the compact" with the states. He announced he has invoked the "Invasion" clause of the Constitution and says Texas has a right to self defense which it will enforce with the Texas National Guard.
Here is Governor Gregg Abbott's Declaration:
I have already told my wife that if this comes down to Civil War, I want us to sell BOTH houses, (NJ & PA) and move immediately to Texas.
