"WASHINGTON - The U.S. Supreme Court on Monday declined to hear a challenge by four environmental groups to the authority of President Donald Trump’s administration to build his promised wall along the border with Mexico.
The justices turned away an appeal by the groups of a federal judge’s ruling that rejected their claims that the administration had unlawfully undertaken border wall projects in Arizona, California, New Mexico and Texas harmful to plant and animal life. The groups had argued that the 1996 law under which the administration is building the wall gave too much power to the executive branch in violation of the U.S. Constitution.
The groups that sued are the Center for Biological Diversity, the Animal Legal Defense Fund, Defenders of Wildlife and the Southwest Environmental Center. They said the wall construction efforts would harm plants, wildlife habitats and endangered species including the jaguar, Mexican gray wolf and bighorn sheep. "
