Construction of a border wall segment has started, despite opposition from a Native American tribe. The tribe claims the work will harm sacred land and accuses the administration of trespassing. A government agency says the area is a smuggling route and the wall will address a security gap.

The project is part of a larger effort to secure the border with walls, barriers, and technology. The total cost of this effort is substantial, and its goal is to curb undocumented immigration.

Further information about the project and its impact is available, including details about the tribe's concerns and the administration's plans.
