She had a vacant demeanor. Trump mentioned her name - no acknowledgement. She didn’t seem focussed on what was going on - her gaze kept wandering around. Clarence Thomas had to help her stand up and supported her while she stood.

I’ve heard her speak recently. Her mind is not sharp as a tack. My 93 year old aunt died 2 years ago and that gal was still sharp. I loved talking with her. She went to sleep and never woke up.
