Hillary Clinton’s sudden departure from a September 11 memorial ceremony on Sunday after becoming “overheated” came two days after she was diagnosed with pneumonia, according to a statement from her doctor that signalled the latest unexpected turn in the race for the White House.
The disclosure comes after campaign aides had insisted for weeks that Mrs Clinton’s chronic cough reflected nothing more serious than seasonal allergies and mocked Republicans who suggested that the former secretary of state was ill.
With only 35 per cent of voters calling Mrs Clinton trustworthy in a new ABC News/Washington Post poll, the episode threatens to erode her slim lead in the polls.
