A candidate who is running to replace U.S. Senator-elect Joni Ernst (R) in the Iowa state Senate has been charged with sexual assault in Nebraska.

Donald Brantz, a 69-year-old Libertarian candidate, was charged with "third-degree sexual assault, third-degree assault, disturbing the peace and interfering with a public service company," the Omaha World-Herald reported on Thursday.

A complaint obtained by the paper said that the charges were related to an Oct 10. incident. Brantz’s attorney did not respond by the time of publication.

Brantz was nominated by the Libertarian Party of Iowa, and filed his candidacy for Ernst’s District 12 seat on Dec. 15.

The Libertarian will face Republican Mark Costello and Democrat Steven Adams in the Dec. 30 special election.
