There is a fully staffed AMBULANCE that follows her motorcade.
Doesn’t have a CT scan, MRI, Echocardiogram. Ambulances are equipped for emergency use.
An ambulance and staff is not capable of testing what needs to be tested in such cases. An ambulance is not a hospital, neither is Chelsea’s apartment. To properly rule out or assess relevant neuro, cardio, and pulmonary problems, they might need x-ray, CT scan, MRI, ultra-sound....
Hillary’s team avoided the hospital because they were confident they already knew what they were dealing with, but that’s risky all the same. There might be newer or bigger problems other than what they think they know about (even if the pneumonia tale were true).
