Hillary Clinton Treated for Pneumonia
After U.S. presidential candidate Hillary Clinton abruptly left a 9/11 memorial service Sunday morning in New York City, her doctor said she was being treated for pneumonia and dehydration.
According to The New York Times, video taken at the event appears to show Clinton, 68, having trouble maintaining her balance as two Secret Service agents helped lift her into a van.
Clinton was first taken to her daughter Chelsea's residence in midtown Manhattan. The Democratic candidate emerged about 90 minutes later, the Times said, waving to reporters and saying "I'm feeling great. It's a beautiful day in New York."
She then joined a motorcade -- without the group of reporters designated to accompany her in public -- and continued on to her home in Chappaqua, N.Y., according to campaign spokesman Nick Merrill.
He told the Times that Clinton was feeling "overheated" during the 9/11 ceremony at Ground Zero, where morning temperatures were in the high 70s with high humidity.
Dr. Lisa Bardack, who examined Clinton in Chappaqua on Sunday, told the Times that Clinton "has been experiencing a cough related to allergies. On Friday, during follow-up evaluation of her prolonged cough, she was diagnosed with pneumonia. She was put on antibiotics, and advised to rest and modify her schedule."
"While at this morning's event, she became overheated and dehydrated," Bardack added. "I have just examined her, and she is now re-hydrated and recovering nicely."
According to the Times, Clinton arrived at the commemoration ceremony at 8 a.m. and left 90 minutes later. Video appears to show her legs giving way as she attempts to walk toward the van. Two Secret Service agents come to her aid and, according to the Times, close-up images seem to show Clinton's feet dragging as the agents lift her into the van.
Clinton has been plagued by coughing linked to allergy attacks since earlier in August, the Times noted. She has acknowledged the health issue, saying that she has been taking antihistamines. "I just upped my antihistamine load to try and break through it," she told the Times. "It lasts a couple days, and then it disappears."
Rumors about Clinton's health have been persistent, but her campaign earlier released a statement from her doctor saying she is in "excellent health."
Speaking to the Times, other attendees at the Sunday morning ceremony said Clinton did not appear ill when she first arrived.
"She seemed fine," said Rep. Peter King, a Republican from New York.
And Senator Chuck Schumer, a Democrat from New York, said he was standing next to Clinton. "It was pretty hot out there, but she seemed fine to me, and left on her own accord," he told the Times.
