Kavanaugh investigators need to see Christine Blasey Ford's therapy records.
She is free to release her therapist's notes to anybody she wants. I can tell you that, as far as psychotherapy goes, I keep few and minimal notes for a multitude of reasons, mostly illegible, and none at all on electronic medical records. Very often, no notes at all. I just follow the process and the progress. Typical therapy note of mine:
"Career issues. Mood ok. Needs a hobby. Same meds. Good session."
