Judge denies tribe request to stop pipeline

Federal judge denies Standing Rock Sioux Tribe's request to stop work on 4-state Dakota Access pipeline.

Despite this ruling, the U.S. government requests Dakota Access pipeline owners `voluntarily pause' work on the section in North Dakota.

The tribe argues the project threatens water supplies and has already disrupted sacred sites.

The developer, Dallas-based Energy Transfer Partners, says modern technology allows quick detection of leaks. Pipeline supporters also say it would cut the amount of oil that travels by train.
