In Nebraska, hundreds of people rallied at the state Capitol Sunday to protest construction of the Keystone XL pipeline, which was resurrected by President Trump as one of his first acts in office. The pipeline has faced years of resistance from Native Americans, farmers, ranchers, landowners and environmentalists. If completed, it would carry 830,000 barrels per day of tar sands from Alberta, Canada, through Montana, South Dakota and Nebraska, where it would join an existing pipeline and carry the oil down to the Gulf.
