Congressman Raul Grijalva (AZ03) has teamed up with the Tucson-based Center for Biological Diversity to sue the Trump administration over the proposed border wall.

The suit seeks to ensure that environmental laws—and all the red tape and studies that come with them—are enforced as Trump moves forward with his beautiful wall.

“American environmental laws are some of the oldest and strongest in the world, and they should apply to the borderlands just as they do everywhere else,” Grijalva said in a prepared statement. “These laws exist to protect the health and well-being of our people, our wildlife, and the places they live. Trump’s wall—and his fanatical approach to our southern border — will do little more than perpetuate human suffering while irrevocably damaging our public lands and the wildlife that depend on them.”

The filing in federal court comes one day after U.S. Attorney General Jeff Sessions used a visit to Nogales to announce new Justice Department policies designed to increase criminal prosecutions of undocumented immigrants.

Center for Biological Diversity Executive Director Kieran Suckling said in a prepared statement that the proposed border wall "will divide and destroy the incredible communities and wild landscapes along the border. Endangered species like jaguars and ocelots don’t observe international boundaries and should not be sacrificed for unnecessary border militarization. Their survival and recovery depends on being able to move long distances across the landscape and repopulate places on both sides of the border where they’ve lived for thousands of years.”
