Standing Rock Sioux Tribe

Demonstrators in Washington, D.C., were urging the Trump administration to meet with tribal leaders, and protesting the construction of the nearly complete Dakota Access Pipeline.

A federal judge denied a request from the Standing Rock Sioux and Cheyenne River tribes to halt construction on the final piece of the pipeline in North Dakota.

The governor of North Dakota had set Wednesday as the evacuation deadline for the largest protest camp. The Trump administration is allowing the pipeline to be built, despite the protests.

An overview of multiple legal challenges and protests since the U.S. Army Corps of Engineers considered approving a section of the pipeline near the Standing Rock Sioux Reservation in North Dakota.

After receiving a long-awaited easement, Energy Transfer Partners has begun drilling the last portion of the pipeline. The work should last 60 days, the company says.

A day after the Army Corps of Engineers blocked the proposed route for the Dakota Access Pipeline, the tribal leader said "nothing will happen" until the Trump administration begins.

Authorities have ordered the protesters of the Dakota Access Pipeline to clear out — but those who have gathered to support the Standing Rock Sioux tribe are preparing for a long stay.

Gov. Jack Dalrymple said Wednesday his emergency evacuation order for areas near the route of the Dakota Access Pipeline did not authorize roadblocks or forcible removal of people.

Gov. Jack Dalrymple cited "harsh weather" in his order, noting that "emergency services probably will not be available under current winter conditions." Protesters have been camped out for months.
