AUSTIN, Texas (AP) – Protesters are demanding that the chief executive of the oil-and-gas company trying to build the controversial Dakota Access pipeline resign from his position as a state commissioner for Texas parks and wildlife.

About 100 people gathered Thursday for a meeting of the parks and wildlife commission in Austin to demand that Kelcy Warren step down.

Warren is CEO of Dallas-based Energy Transfer Partners, which wants to build a 1,172-mile, $3.8 billion pipeline that would carry oil from North Dakota through South Dakota and Iowa to a shipping point at Patoka, Illinois.

American Indians and others have demonstrated against the project for months.

Protesters waved banners Thursday in Austin seeking Warren’s resignation.

He was appointed to the commission last year by Gov. Greg Abbott.
