US Republican presidential candidate Donald Trump has pledged torelease details about his health after his Democratic rival Hillary Clinton was diagnosed with pneumonia.
Mr Trump said health had now become "an issue" in the election campaign.
Mrs Clinton was taken ill on Sunday at a 9/11 memorial ceremony and cancelled a campaign trip to California.
Mrs Clinton had "overheated" but was now re-hydrated and was "recovering nicely", her doctor said.
Mr Trump wished her a speedy recovery and said he would release the results of a medical examination he took over the past week, with "very, very specific numbers".
"Hopefully they're going to be good. I think they're going to be good. I feel great," he told Fox News.
So far Mr Trump has only released a note, in which his doctor declared that he would be "the healthiest individual ever elected to the presidency".
Mr Trump, 70, and Mrs Clinton, 68, are among the oldest US presidential candidates in history.
