Sen. Tom Udall, D-N.M., marked the second anniversary of the Gold King Mine disaster by calling it an “injustice” that the Environmental Protection Agency caused but has yet to rectify.

The Aug. 5, 2015 spill at the abandoned gold mine in Colorado sent 3 million gallons of toxic waste water and sludge into the Animas River, sullying the waterways of three states. Yet, as the Democrat recalled in a statement Saturday, the Navajo Nation, farmers, ranchers, and local communities harmed by the disaster are “still waiting for our government to make them whole.”
