The winding Rio Grande river is the natural dividing line between the U.S. and Mexico in southern Texas.
Yvette Gaytan’s family has owned land on the border's edge for generations. Her kids fish along the river banks in Starr County.
The Trump administration has asked to use Gaytan’s land to build sections of the wall approved in the newly passed budget.
“I’m not looking to sell. I’m not looking to move,” she told ABC News. “My father helped build this house with his own two hands.”
Not far from her home, President Donald Trump’s long-promised southern border wall continues to be a work in progress. Crews have now started preparing to build the first new miles. Further east, old barriers have been replaced with new ones.

His battle with Congress, which resulted in the longest government shutdown in American history, left him with fewer funds to build the wall in places like Starr County.

“We’re at the very beginning of what’s probably going to be a long, drawn-out process,” said Public Citizen lawyer Michael Kirkpatrick.
In order to stop the construction, Kirkpatrick will have to wait for the Trump administration to figure out how it will fund the planned sections of the wall. But he says it's clear that any wall would hurt all of his clients.
The Trump administration has plans to build as many as 12 miles of new border wall in Starr County. It’s a massive steel fence design, 20 to 30 feet high. U.S. Customs and Border Protection is involved in a variety of legal disputes over these projects.

“Put more people on the ground, put boots to the ground,” she said.
But from her land overlooking Mexico, she doesn’t see a national emergency, and leaving her family’s legacy behind would be a devastating outcome, she says, adding, "I’m not going to go down without a fight.”
