But by his own admission, he was having drinks in her apartment and at least tried to kiss her. Maybe it's all a big misunderstanding or they just got their signals crossed, but it's not like he can say wasn't me, she has the wrong guy. Something happened.
But why the headlines 20+ years later? If she was assaulted, call the cops or file a lawsuit within the statute of limitations. Personally, this parade of people publicly emerging DECADES after the alleged occurrence of an event makes me yawn. If it wasn’t important enough to mention 20-30 years ago, what makes it important today??
