Protesters have gathered Tuesday afternoon in Downtown Dallas to voice their opposition to the Dakota Access Pipeline.
Dallas-based Energy Transfer Partners is building the 1,200-mile pipeline, which is designed to carry oil from North Dakota through South Dakota and Iowa to a shipping point in Illinois at a cost of $3.8 billion.
However it runs under a reservoir that provides drinking water to the Standing Rock Sioux tribe in North Dakota, which says the pipeline threatens drinking water and other cultural sites.
Protests have been ongoing for months and are expected to spread across the U.S. to other cities, including outside the Earle Cabell Federal Building in Dallas.
About two dozen protesters plan to march and rally, and speakers include recent visitors to the protest at Standing Rock.
The U.S. Army Corps of Engineers called Monday for more study and input from the Standing Rock Sioux before it decides whether to allow the pipeline to cross under the water reservoir, Lake Oahe.
Energy Transfer Partners and a subsidiary are asking U.S. District Court in Washington, D.C., to confirm the company has the legal right to proceed.

The latest news from around North Texas.
The Corps in July granted ETP the permits needed for the crossing, but it said in September that further analysis was warranted given tribal concerns.
ETP says additional delay amounts to politic interference and says it will "vigorously pursue its legal rights."
