I believe the Texas AG is warning the monitors of the Texas' statutory 100 feet polling place perimeter. I.e. unless you are actually voting, standing in line to vote or are a poll worker, you can't come inside 100 feet of the entrance to a polling place. In many states, it's considered an anti-electioneering measure. In others, it's a anti-intimidation measure.

And by the same measure, I assume Texas law does not make provision for persons other than voters and election officials to be inside a polling place.
