(Adds AGM voting campaign) By Byron Kaye SYDNEY, Oct 15 (Reuters) - A director of Australia's Crown Resorts Ltd CWN.AX told an inquiry she felt pressured by its then-chairman to sign a now-discredited newspaper advert attacking negative media coverage, just as shareholders on Thursday called for her to be voted out. Jane Halton, a former top bureaucrat who sits on several company boards and chairs global vaccine advocate Coalition for Epidemic Preparedness Innovations, said she later became aware the ad featuring her signature contained false information.
