He could start by attacking her credibility. If she was harassed a decade ago, why is she just spouting off about it now? Seems to me she may be nothing but a gold digger looking to get in on some publicity and maybe a cash payout.
If I were Herman I'd say that she was the one that offered him a lewinsky if he would get her a job, and he told her that he was happily married and told her to go away.
She tried to plunge her head into his lap, but he fought her off.
Say that if she doesn't apologize by 6:00 PM he is going to bring charges of slander against her, and if she doesn't, then bring them.
There is a nugget of truth in there someplace.
