"PHOENIX — The U.S. government plans on replacing barriers through 100 miles (161 kilometers) of the southern border in California and Arizona, including through a national monument and a wildlife refuge, according to documents and environmental advocates.
The Department of Homeland Security on Tuesday again waived environmental and dozens of other laws to build more barriers along the U.S.-Mexico border.
Funding will come from the Defense Department following the emergency declaration that President Donald Trump signed this year after Congress refused to approve the amount of border wall funding he requested."
