Bardack, Clinton’s physician for more than a decade, said in her statement that the Democratic nominee’s cough was related to allergies and the pneumonia was diagnosed during an evaluation of the cough. The physician said Clinton has had an allergy-related cough, and that during a follow-up examination Friday, the candidate was diagnosed with pneumonia, put on antibiotics, advised to rest and modify her schedule. A video showed Clinton slumping and being held up by three people as she was helped into a van after the event, and her doctor said in a statement that Clinton had become overheated and dehydrated. “It’s a beautiful day in New York.”

Mrs. Clinton left in her motorcade without the group of reporters that is designated to travel with her in public. A campaign spokesman, Nick Merrill, indicated that she had returned to her Chappaqua, N.Y., residence sometime after 1 p.m., and Mrs. Clinton was not seen publicly the rest of the day. The most notable events in Clinton's medical record included deep vein thrombosis - or a blood clot, usually in the leg - in 1998 and 2009, a broken elbow in 2009 and a concussion in 2012.
Hillary Clinton's doctor says she is being treated for pneumonia and dehydration after the Democratic Party presidential candidate fell ill and abruptly left a ceremony in New York City honoring the 15th anniversary of the September 11 attacks.
