IMO they are holding out for her to testify. Pressure is on her. If she testifies to what we’ve heard already she perjures herself and Di Fi is in trouble for pushing her testimony. Most of the senators are simply saying “we want to hear her — all victims need to be heard”. This does not mean they will not vote to confirm K. The burden of proof is STILL with her. All victims should be heard but not all will be believed.
That being said there are the witnesses who refute her claim, the calendars, the testimony of his friends and the judges own testimony.
