SHAWNEE, Kan. (AP) — A local GOP official has resigned his party post in Kansas after fellow Republicans condemned his social media attack saying a Native American congressional candidate would be “sent back packing to the reservation.”

The Kansas City Star reports that Michael Kalny of suburban Kansas City resigned Wednesday as a Republican precinct committee member.

In his Facebook message, Kalny called Democratic candidate Sharice Davids a “radical socialist kick boxing lesbian Indian.” He sent the message Monday to the president of a local Democratic women’s group.

Davids is an LGBT lawyer and member of the Wisconsin-based Ho-Chunk Nation running against Republican Rep. Kevin Yoder. She also has fought mixed martial arts bouts.

Yoder’s spokesman and the Kansas GOP’s executive director repudiated Kalny’s remarks. Kalny did not return a telephone message seeking comment.
