Okay ... I don’t want to be one of those nabobs of negativism ... but the Case/Picture you pasted is NOT the Texas case.
So far I have been able to find direct evidence of LA, AR and AL joining or at least supporting (in the case of AL) the Texas case.
Hope I’m missing something!
There ought to be at least 25 states joining this lawsuit (and possibly there will be).
Traction.
BREAKING. Eight More States Join the Texas SCOTUS Case [Taking A Deep Breath]
Now it is no longer Ken Paxton playing Lone Ranger. The addition of eight states to the lawsuit now means that nearly a third of the states are litigants, and the Supreme Court’s ability to blow this off as nothing shrinks dramatically.
