Pretty simple solution, you want your story heard, the hearing is on Thursday at 10 am. be there by 9 to get through security. See ya then or not ever. You will be under oath and you will be subject to perjury charges.
If I were Grassley I would just announce that this entire thing is a charade and hold the vote tomorrow.
Note that in McConnel's speech yesterday he promised and up or down vote, but he's no longer saying Kavanaugh will be on the court.
Not confirming Kavanaugh is McConnel's and Grassley's way to make this go away since Kavanaugh won't withdraw. It's all about protecting their asses and they don't care who is discarded along the way.
