The wall could seal some Americans on the “Mexican side” — technically on U.S. soil, but outside of a barrier built north of the river separating the two countries. Landowners could lose property, and those that already lost some for the existing fence are already preparing for a new battle.

“That’s a fight that we’ve been ready to fight,” said Efren Olivares, a lawyer with the Texas Civil Rights Project.
