KANSAS CITY, Mo. -- A group in downtown Kansas City is gathering to support the Standing Rock Sioux Tribe's fight to stop the Dakota Access Pipeline.
There are people protesting nationwide outside Army Corps of Engineers offices in solidarity with the protesters in North Dakota.
The Standing Rock Sioux say they are fighting over the pipeline's potential impact on sacred sites and water contamination.
The US Army Corps of Engineers has delayed the construction of the pipeline until it meets with the tribe.
The proposed $3.7 billion pipeline would stretch from North Dakota through the Midwest and onto the Gulf coast. Oil companies want to tunnel under Lake Oahe, which is part of the Missouri River.
The companies say the pipeline is a more efficient way to transport North Dakota oil instead of using trucks and trains. The Standing Rock Tribe fears the pipeline could rupture and pollute the water supply and would destroy a sacred tribal site.
"We are all downstream so a major spill into the Missouri by the standing rock reservation could very well affect our water supply here," says John Fish Kurmann with 360 KC, a climate action movement.
The Army Corps of Engineers hopes to meet with the tribe to discuss ways the easement for the pipeline which is adjacent to the Standing Rock Sioux Nation could reduce spills.
