Are the barriers on private property? If so, that seems a violation of many things? But, if on fed property then TX may not be able to keep them there. But, I cannot imagine a single land owner in TX who would not let the state of TX move the barriers to their property line.
Not that I agree in any way about the massive influx of illegals, but I could also see how a cease and desist order could be enforced if the barriers are on fed property.
