Ignoring protests by environmentalists and Native American activists, Trump signed executive orders approving two controversial pipelines. The Keystone pipeline was opposed by environmental activists and rejected by the Obama administration in 2015. The Dakota Access pipeline was fought by the Standing Rock Sioux tribe because it cuts through their ancestral lands and endangers their water supply. The Obama administration halted work on the Dakota pipeline only recently. Trump approved both pipelines to create jobs and please the fossil fuel industry.
