American Indians from around the country are bringing their frustrations with the Trump administration and its approval of the Dakota Access oil pipeline to the nation's capital.

Tribal members will gather on the National Mall Tuesday to begin four days of activities.

The week culminates Friday with a march to the White House dubbed the "Native Nations March on DC."

Tribal members and supporters plan to camp each day on the National Mall, with teepees, a ceremonial fire, cultural workshops and speakers. Native American leaders also plan to lobby lawmakers to protect tribal rights.

The protest comes as a federal judge in Washington is weighing a request by the Standing Rock and Cheyenne River Sioux tribes to halt construction of the last section of the pipeline.
