This article is from the libertarian-leaning Reason magazine article, not exactly an outlet known for pro-Biden propaganda. There's no witnesses, her friends say she's attention-seeking, and she has a history of praising Biden in tweets. If you were sexually assaulted by your former boss would you be praising him on Twitter and wishing him a happy birthday?
I find this women making claims against Biden has no credibility.
Similarly the women making claims against Kavanaugh have no credibility either. His confirmation hearing was a disgrace on the part of Democrats.
