Heard spin by Fox earlier. Her testimony about the limo was second hand. SS said ready to testify Trump didn’t “lunge”
It was second hand, or hearsay, and she admitted to that. That makes that entire story less credible, but the fact that she said upfront that it was a second hand story means that her credibility is still intact. She didn't claim it was true, only that it is something she was told.
It is worth point out that at this time the SS version of the story is also hearsay, and has even less credibility as her story. We don't know where the SS version comes from, while her version is able to be vetted. Until they actually testify to that it is just a rumor.
My takeaway is that we should be skeptical about that particular story until it is vetted either way, but that no matter if it is true or not it does not effect the her credibility.
Of course the Right are going to try to use it to discredit her, and because a lot of people are really poor at critical thinking it will work. But it does not really matter, they would have used something to discredit her no matter what, even if they had to make it up whole cloth.
