If you take the time to research Tara Reade's claim I think it's fairly obvious which parts are likely true and which parts are likely false.
Reade worked for Biden in the early 90s and claims that he sexually harassed and sexually assaulted her when she was working for him in 1993.
Parts of her claim are credible and parts are not.
She told multiple people including her mom that she was having issues with Biden, and that's why her mom called Larry King Live in 1993. She also stopped working for Biden nearly a month after the said incident and their are many people who report that Reade told them she was having issues with Biden when she was working for him, Biden is a piece of shit and he did likely sexually harass Reade, their is no other explanation for her mom's call to Larry King live.
I don't believe Biden sexually assaulted Reade though. Reade has tweeted support for Biden, including on women's issues for years after the alleged assault. Read's mom also called Larry King to say her daughter was having an issue with a Senator, her mom's tone was very casual, and no one would call in to say someone was having an issue if they were assaulted, that would be more than an issue obviously.
Also, Reade claims she filed a complaint about Biden over the alleged assault in 1993 but their was never any police report or subsequent investigation until Reade recently field a police report about a year ago. This is inconsistent with Reade's claim that the complaint she filed was over sexual assault. If Reade had filed a claim alleging a serious crime the claim would have likely been referred to the DC Police or the FBI for a criminal investigation, the Senate does not investigate crimes, that's what the FBI and police departments are for. Reade also received a lot of money recently that kept her from having to file bankruptcy and has never alleged sexual assault against Biden until recently despite commenting on Biden for nearly 25 years. Reade was likely sexually harrassed by Biden and then paid to say she was sexually assaulted once it was clear Biden would be the nominee. The tone of her mom's call and the fact that their was never any referral for a criminal investigation despite her claim she filed a report suggests Reade was not the victim of a serious crime. It doesn't make sense she would compliment Biden for his work, including his work on womens rights issues if she was sexually assaulted either.
Biden's interview with MSNBC was interesting, hew as careful to distinguish between sexual harassment and sexual assault, almost admitting that he understands why Reade felt she was sexually harassed by Biden when working for him in the 90s.
The democrats, including Biden pushed the absurd allegations of people like Blasey Ford with far less evidence than Reade, and Biden can't admit anything, including sexual harassment, because it gives Reade credibility, so it would be interesting to see what happens here.
