It may be a coverup but I can believe that she has pneumonia. That is usually what the cause of death is in advanced stage of Parkinson’s disease.

There's no way in hell Hillary would have been at the memorial service today, if she truly has pneumonia. If true, she should be in a hospital.
Her doctor claims she made the pneumonia diagnosis on Friday, yet that evening Hillary was at a fundraiser calling Trump supporters, "deplorables".
AND - an hour after her health episode today, she was on the street outside Chelsea's apartment telling the press, "I feel fine!"
Total load of bull. She's sick, but not with pneumonia. They're still trying to cover up her real health issues.
