She was supposed to campaign in San Francisco and Los Angeles to start this week and tape an appearance for the “Ellen” show. 

Clinton has been ill with pneumonia, her doctor revealed in a Sunday evening statement.

Dr. Lisa R. Bardack released a statement via the campaign revealing the diagnosis on Sunday evening, hours after Clinton was seen stumbling on video after exiting a 9/11 memorial event early.

Bardack said Clinton had an examination at her home in Chappaqua, N.Y., after the incident, which was a result of dehydration and overheating. 

She said the candidate is "re-hydrated and recovering nicely."
