The Dakota Access Pipeline is back in business

The Army Corps of Engineers has done a 180 on the Dakota Access Pipeline, turning victory into another battle for Native Americans.

Just two months ago, tribal leaders and many supporters were celebrating a victory when the Army Corps of Engineers ordered an environmental impact report on the Dakota Access Pipeline. Now, the Corps has reversed itself, and construction is under way again for a tunnel under the Missouri River just upstream from the Standing Rock Sioux Reservation.
