A border construction project near Big Bend is now at the center of a dispute between the state of Texas and the federal government after Texas Land Commissioner Dawn Buckingham accused a federally hired contractor of clearing state-owned land without permission.

Texas issues cease-and-desist over border wall What we know: Buckingham sent cease-and-desist letters this week to U.S. Customs and Border Protection, the company leasing the property, and a subcontractor.

She says this is not a fight over border security, but control over Texas land.
