A San Diego businesswoman told CNN Wednesday that Mayor Bob Filner put his hands on her buttocks at a meeting.
Diane York, the 18th woman to allege that Filner improperly touched her, told CNN that Filner touched her backside during a photo opportunity after the meeting three months ago. York is scheduled to hold a press conference at 1 p.m. PST Wednesday, according to San Diego's KGTV.
A 17th accuser, real-estate agent Caryl Iseman, had said during a rally Sunday that Filner grabbed her breast at a fundraiser 25 years ago, according to San Diego Gay and Lesbian News.
Filner's lawyers have been in mediation talks since Monday as the mayor faces both a sexual harassment lawsuit filed by his former communications director and a vocal recall effort. The Democratic National Committee will vote on a resolution that would call Filner's resignation, CNN reported Tuesday.
