U.S. Senators Katie Britt, Tommy Tuberville, Bill Hagerty and Tim Kaine sent a letter to Mexican Foreign Affairs Secretary Alicia Bárcena urging action against the Mexican government's ongoing harassment of Vulcan Materials.

The letter marks two years since the Mexican government invaded and closed Vulcan's deep-water port of Punta Venado in Quintana Roo. Since the invasion, Mexican President Andrés Manuel López Obrador has repeatedly threatened to expropriate the company's port and limestone quarries, despite the company's 35-year presence in Mexico.

“President Lopez Obrador's actions threatening Balkan's legitimate operations in Mexico are unacceptable and illegal under Mexican and international law. Major infrastructure projects in Alabama and throughout the southeastern United States continue to be put at risk by the lawless actions of the Mexican presidential administration,” said Senator Britt (R-Montgomery).

“I will always defend the economic and security interests of Alabama and the United States, and I urge the Mexican government to find a constructive path forward that does not further jeopardize bilateral relations.”

Last March, the Alabama delegation met with Ambassador Moctezuma to defend Vulcan in its dispute with Mexico. The delegation subsequently announced that Mexican troops had withdrawn from Vulcan Materials Company's port facility in Mexico and that Mexican law enforcement had also withdrawn from the facility.

“Alabama is proud to be home to the world-renowned Vulcan Materials Company, which has provided good-paying jobs to thousands of Americans since it was founded more than 100 years ago. We've also operated environmental award-winning operations in Mexico for more than 30 years, driving economic growth in the region,” said Sen. Tuberville (R-Auburn).

“The Mexican government's hostility towards Balkan is unjustified and puts at risk the longstanding bilateral relationship between Mexico and the United States. I will continue to fight for the prosperity of American businesses and hope for a swift and fair resolution to this situation.”
