DES MOINES, Iowa (AP) — A woman has filed an ethics complaint against Iowa legislator Nate Boulton, detailing allegations she initially made in May that led the lawmaker to drop his campaign for governor. The Des Moines Register reported Monday the woman filed the complaint Saturday with the Iowa Senate. The complaint alleges that one night at a bar in November 2015, Boulton repeatedly grabbed her buttocks.

The Register had previously reported the woman’s allegations as well as allegations from two other women regarding incidents more than a decade ago. After the stories were published, Boulton dropped his bid for the Democratic nomination for governor. Despite calls that he resign, Boulton opted to remain in the Senate.

Boulton couldn’t immediately be reached for comment. The chairman of the Senate ethics committee also wasn’t available.
