Yet Biden, now the presumptive Democratic presidential nominee, was also a toucher, seemingly oblivious to whether physical contact made some women uncomfortable. That behavior has persisted in recent years. Biden is now facing fresh scrutiny after a former aide in March charged that he sexually assaulted her when she worked in his Senate office in the early 1990s, an allegation Biden has categorically denied.

The PBS NewsHour spoke with 74 former Biden staffers, of whom 62 were women, in order to get a broader picture of his behavior toward women over the course of his career, how they see the new allegation, and whether there was evidence of a larger pattern.

None of the people interviewed said that they had experienced sexual harassment, assault or misconduct by Biden. All said they never heard any rumors or allegations of Biden engaging in sexual misconduct, until the recent assault allegation made by Tara Reade. Former staffers said they believed Reade should be heard, and acknowledged that their experiences do not disprove her accusation.
