It’s kinda Captain Obvious that she’s had serious health problems for awhile now.
She might want to stop her insurrection tour and get rest. Frankly, it didn’t look like she was going to make it way back in September, 2016. She’s obviously not a healthy person.
She is 70 years old and morbidly obese. She had a severe concussion which damaged her eyesight such that she had to wear glasses with fresnel lenses to correct her sight. She never should have attempted those stairs.
