Thousands of people in North Dakota are protesting the construction of the pipeline. They have been camped out at the site for months, and they call themselves "water protectors," not protesters.

The $3.8 billion pipeline doesn't quite cross the Standing Rock reservation, but it will cross the Missouri River  less than a mile from the reservation.

The Army will now decide whether to reconsider the path of the pipeline's construction. Until then, the project is on hold.
