In Arizona, Tohono O’odham land and water defenders led a protest Monday, blocking the border wall’s construction for several hours near a sacred spring inside the Organ Pipe National Monument. Protesters carried a banner that read “Borders = Genocide, No Wall on O’Odham Land.” National Park Service and Border Patrol agents on the scene started shoving protesters, forcing them to disperse after an hours-long standoff. Wall construction crews in the Sonoran Desert have destroyed pristine landscape and pumped millions of gallons of groundwater, used to mix cement, for Trump’s wall.
