WASHINGTON DC —
U.S. Democratic presidential candidate Hillary Clinton is skipping a campaign trip to the western state of California after being diagnosed with pneumonia.
A spokesman announced late Sunday she would not be making the previously planned trip that had included fundraisers and a speech about the economy on Monday and Tuesday.
The Clinton campaign said a doctor had examined her Friday because of a prolonged cough and she was told then she had pneumonia. Her doctor gave her antibiotics and advised Clinton to rest and modify her schedule.
Her Republican opponent, real estate mogul Donald Trump, told Fox News that he hopes Clinton gets well soon. Trump said he plans to release the results of a physical exam he had during the past week, with "very, very specific numbers."
"I hope she gets well and gets back on the trail and we'll be seeing her in the debate," Trump said, referring to their scheduled first face-to-face encounter on September 26.
Clinton, at 68, and Trump, at 70, are among the oldest candidates ever to seek the U.S. presidency. To date, they have not released extensive records about their health, although she has provided more information than he has.
Now, with her pneumonia diagnosis, some U.S. political analysts are calling for both candidates to disclose more of their health care records from over the years.
Clinton's pneumonia diagnosis was not made public until Sunday after she appeared unsteady at a September 11 commemoration ceremony in New York. She abruptly left the event recalling the terrorist attacks against the United States 15 years ago and a video showed her stumbling off a curb and being helped by Secret Service agents and aides into a van.

Clinton's doctor said later she had become "overheated and dehydrated" but was "recovering nicely."
Clinton later emerged from her daughter Chelsea's apartment where she waved to supporters.
"I'm feeling great. It's a beautiful day in New York," Clinton said as she left in her car.
Questions about stamina
With the U.S. presidential election less than two months away, the issue of Clinton's health is likely to linger. Trump has cast Clinton as lacking the stamina necessary to handle the job and he and some of his supporters have suggested, without providing evidence, that she is seriously ill from the after-effects of a concussion she suffered in a fall in 2012.
At the time, doctors found a blood clot on her brain and she temporarily suffered from double vision, before her physicians said she had fully recovered.
Last year, Trump released a letter from a physician claiming he would be "the healthiest individual ever elected to the presidency."
The doctor, however, has since acknowledged he dashed off the note in five minutes while a Trump campaign limousine waited nearby.
