BISMARCK, N.D. (AP) — An oil industry group says U.S. Interior Secretary Ryan Zinke has been invited as the keynote speaker for the Williston Basin Petroleum Conference that will be held next month in Bismarck.

The conference is scheduled May 22-24 at the Bismarck Event Center.

The 26th annual event will feature dozens of speakers, from politicians to top oil company executives, and industry-specific seminars.

The North Dakota Petroleum Council says more than 2,500 people are expected at this year’s conference.

The event has alternated in recent years at locations in North Dakota and Canada.
