CANNON BALL, ND - DECEMBER 03:  Angie Spencer (L) performs sage smudging on a Military veteran at  Oceti Sakowin Camp on the edge of the Standing Rock Sioux Reservation on December 3, 2016 outside Cannon Ball, North Dakota. As many as 2,000 veterans are expected at the camp this weekend to participate in non-violent protests against the construction of the Dakota Access Pipeline. Native Americans and activists from around the country have been gathering at the camp for several months trying to halt the construction of the pipeline. The proposed 1,172-mile-long pipeline would transport oil from the North Dakota Bakken region through South Dakota, Iowa and into Illinois.  (Photo by Scott Olson/Getty Images)
