DES MOINES, Iowa -- Construction on the Bakken oil pipeline is already underway but those who are against it are making a cross-country effort in hopes of stopping its progress.
"The run is challenging but the status is what makes us push more," William Brownotter said.
Members of the Lakota and Dakota tribes are running 2,000 miles from North Dakota to Washington D.C. to protest the project.
The tribes worry that once the pipeline is built, it will leak oil and contaminate the rivers they drink from.
Once in D.C., they will call for the Army Corps of Engineers to look into the harmful impact the pipeline could cause.
"It's been an exhausting battle for those of us who have been fighting this for nearly two years and you get used to it after a while," Ed Fallon said. "We`re up against a lot of money and a lot of power and a lot of greed and the best you can do is keep firing away by raising the truth and helping people understand the real issues."
The pipeline will run through 18 Iowa counties.
