I hope she hasn’t bought a plane ticket yet. She won’t be needed.
The format for the hearing has been set and it may well indeed intiminate her and she will stay away. The format has her going first with questioning by Mitchell or the Pub senators. Each senator has 5-minutes to ask her questions and may give that time to Mitchell. After the questioning of Blasey Ford, the same process is repeated for Kavenaugh. I suppose Dem senators may use her, but I suspect most questions will be by the Senators themselves.
