Some Democrats say that’s likely not unintentional, arguing that a high-profile endorsement of Biden by Bill Clinton would be off-key as the former vice president deals with a 1993 charge of sexual assault from a former staffer.

“Talk about a man who doesn’t fit the moment,” said one longtime Democratic fundraiser.

Biden has denied the charge, saying the incident never happened. And his campaign has become more aggressive in pushing back, arguing ex-staffer Tara Reade has changed her story and scolding the media for not digging into the issue further. Reade in an interview this week said Biden should drop out of the race for the White House.
