We are not going silently into the night,” declared Bernie Sanders as he rallied outside the White House this week with opponents of the Dakota Access pipeline. (Sanders) made a surprise appearance at the Tuesday-night protest to highlight concerns about climate change, telling the crowd that “The stakes are too high for the future of this planet. We are going to be smart. We’re going to educate. We’re going to organize. We’re going to bring tens of millions of people, moms and dads and their kids, together, together, to tell the fossil fuel industry that their short-term profits are not more important than the future of our planet.” While the pipeline debate was his focus on Tuesday night, he was taking up the cause of the working class on Wednesday night and joining nurses in defending Medicare and Medicaid on Thursday.
