SIOUX CITY, Iowa (AP) — A presidential campaign event focused on Native American issues is being planned in Sioux City, Iowa, next month.

Several groups are working together to plan the forum on Aug. 19 and Aug. 20.

O.J. Semans of the voting rights group Four Directions says it would be a mistake for candidates to ignore Native American voters.

The Sioux City Journal reports that organizers are working to get firm commitments from candidates to attend.

The event is named in honor of activist Frank LaMere, who died last month after battling cancer. He was a Winnebago Tribe of Nebraska member who fought for a variety of causes. He lived in South Sioux City, Nebraska.
