The project aims to transport crude oil from the North Dakota Bakken region through South Dakota and Iowa into Illinois, crossing the Missouri River.

In the video posted by, an online petition platform, Miller says: "As a gang of earth defenders, we want to send a big shout out to the Oceti Sakowin and those who stand with them in opposing the Dakota Access Pipeline."
