"WASHINGTON - The U.S. Supreme Court on Monday rebuffed a challenge by three conservation groups to the authority of President Donald Trump’s administration to build a wall along the U.S.-Mexico border, a victory for Trump who has made the wall a centerpiece of his hardline immigration policies.

The justices’ declined to hear the groups’ appeal of a ruling by a federal judge in California rejecting their claims that the administration had pursued border wall projects without complying with applicable environmental laws. The groups are the Center for Biological Diversity, the Animal Legal Defense Fund and Defenders of Wildlife.

Their lawsuits said construction operations would harm plants, rare wildlife habitats, threatened coastal birds like the snowy plover and California gnatcatcher, and other species such as fairy shrimp and the Quino checkerspot butterfly."
