An affair may not have ever happened. I truly have no opinion on that. But I can speak from experience that attorneys do sometimes "make it go away" for their client. Famous people can fall victim to "nuisance" lawsuits. The famous person can be totally innocent of whatever they are accused of, but their legal team will "throw some money at it" , have the accuser sign a NDA, and poof, it's gone. Saves time, money (of defense) and face. Happens way more than we all think.
Adding for clarity, I'm a Bernie fan
