The unearthed 1993 Larry King Live clip that proved that Tara Reade did indeed disclose some sort of “problems” with working for Joe Biden made her initial allegation of sexual harassment credible. A blockbuster report from Rich McHugh at Business Insider has now made her allegation of a sexual assault in the form of forced penetration by hand credible as well.

Until now, the three living corroborative witnesses have either been too press-shy or shifty to trust fully. But McHugh found a crucial fourth witness, Reade’s former neighbor Lynda LaCasse. A self-described Biden supporter, LaCasse claimed that in 1995 or 1996, just two or three years after the alleged assault, Reade specifically said that Biden had assaulted her, not harassed her.
