Over the weekend, military veterans joined Native Americans and activists at the camp in North Dakota – now amid heavy snow – where they’ve spent months trying to stop construction of the Dakota Access pipeline. Then, on Sunday, the US Army Corps of Engineers announced it would not allow the pipeline to run under a lake on the Sioux Tribes Standing Rock reservation. It remains to be seen whether the decision will be reversed next year when Donald Trump becomes president. The proposed 1,172-mile-long pipeline would transport oil from the North Dakota Bakken region through South Dakota, Iowa and into Illinois.
