(AP) — The president of the Oglala Sioux Tribe is scheduled to visit Lincoln next week to discuss alcohol sales in the Nebraska town of Whiteclay, on the border of South Dakota’s Pine Ridge Indian Reservation.

Tribal President Bryan Brewer will give a speech Sunday at Vine Congregational United Church of Christ in Lincoln. The 7 p.m. event is free and open to the public.

Organizers say Brewer is also planning to meet with Nebraska Gov. Dave Heineman to talk about alcohol sales in Whiteclay. Activists say the town’s beer stores contribute to social problems on the officially dry reservation.

Last year, Brewer spoke at Chadron State College in northwest Nebraska about his plans to attract small businesses to the reservation while preserving the tribe’s Lakota language.
