Well, my guess is the Dems are desperately searching for someone who is willing to commit perjury and say that they were at the party and saw the accuser crying, or some such. Alternately they might be trying to get someone on the stand to commit perjury and say they were also attacked by Kavanaugh.
The accuser is clearly working with the Dems, and Grassley and the other Republicans on the Judiciary Committee are fools for being led around by the nose and letting this dog and pony show go on.
They know she is a few fries short of a happy meal.
