I'm not talking about her having to do any jail time. I'm just trying to emphasize that her testimony will appear to be... ummm... less than credible, if these people she claims told her these things in her testimony, come forth and testify themselves that they NEVER told her any of it. It will be hearsay. "He told me Trump did this!" "No, I never told her anything." There's nothing there that will hold up in any court, let alone public opinion. If they DON'T testify, then it will be a different situation. However, for people who approve of DJT, what she has said are all lies. Of course, they wouldn't believe anything he did that might paint him in a negative way.
The details about what happened in the Beast was all second-hand. Someone allegedly told her what happened. She didn't actually see anything. I'm not sure how well that will hold up in any legal context. Maybe it will, I just don't know. Personally, I don't think he had the balls to actually be there at the capitol, in person.
