Hillary has pneumonia: Clinton's doctor reveals she has a lung infection - hours after her aides blamed the 68-year-old's collapse on 'overheating' when it was caught on video at 9/11 memorial service

The Democratic presidential candidate is seen standing on a curb (inset) near the World Trade Center when she appeared to lose her balance.


One of her aides is seen grabbing onto her arm as the motorcade arrives. Her security detail then had to help her into her van before she was driven to daughter Chelsea's nearby apartment. Despite the concerning footage, she  emerged from the home at 11:45 on Sunday saying she was fine. She told waiting reporters: 'I'm feeling great, it's a beautiful day in New York'. A smiling Clinton was then greeted by a young girl on the street to pose for a picture. She then waved  at customers at a nearby restaurant before getting into a van. Nick Merrill, her travelling press secretary, said Clinton 'overheated' during the ceremony, but had quickly recovered. But the video seems to show her symptoms are far worse than her aides have suggested.
