Hillary Clinton`s doctor endorses her fit to serve as US President Democrat Presidential hopeful, Hillary Clinton has been declared healthy and fit to serve as US president by her doctor. This follows a release of an update on her medical information by her campaign. The statement said Mrs Clinton continues to improve after a pneumonia diagnosis. The disclosure came as her Republican rival Donald Trump released health data of his own on a medical chat show. Clinton aides say she will return to the campaign trail today, after falling ill in public at the weekend. Both candidates, among the oldest ever to run for the White House, have been under intense pressure to share more medical information. Health issues have dominated the race for November's election since a dizzy spell forced Mrs Clinton, 68, to leave a 9/11 ceremony in New York on Sunday. BBC
