Endangered Butterfly, Mexican Shrub May Be Hurdles to Trump’s Wall

Environmentalists suing to block President Donald Trump from constructing a wall along the Mexican border say the project would imperil endangered species including the Quino checkerspot butterfly and the Mexican flannel bush.

The Homeland Security Department has asserted authority under federal immigration law to waive compliance with environmental protection statutes because 14 miles of existing fencing near San Diego is “no longer optimal for border patrol operations.”

Defenders of Wildlife, the Animal Legal Defense Fund, the Sierra Club and the Center for Biological Diversity argued in court filings this week that the Trump administration’s attempts to sidestep the National Environmental Policy Act and the Endangered Species Act are unconstitutional.

A hearing over the dispute is set for February before U.S. District Judge Gonzalo Curiel, whom Trump scorned during the presidential campaign over the San Diego jurist’s handling of the Trump University fraud litigation. Trump attacked Curiel as being biased against him because of his Mexican heritage, saying the Indiana-born judge had issued rulings against him as retribution for his pledge to build a wall between the U.S. and its neighbor to the south.
