The Department of the Interior stated that it had no records responsive to American Oversight's request for assessment or analysis of the impact, including the impact on endangered species, of building a wall along the U.S.-Mexico border.
American Oversight obtained documents from the U.S. Fish and Wildlife Service concluding that a border wall would cause "serious and likely irreparable" damage to the refuges in the lower Rio Grande River valley and would undo tens of millions of dollars in investments made in stabilizing those refugees.
Government records obtained by American Oversight show that officials at the U.S. Fish and Wildlife Service have concerns about the potential environmental impact of President Trump's proposed all along the U.S.-Mexico border.
