Clinton cancels California trip after health scare: campaign

NEW YORK - Democratic White House hopeful Hillary Clinton cancelled a campaign fundraising trip to California after she fell ill at a 9/11 memorial ceremony Sunday and her doctor revealed she was diagnosed with pneumonia.

"Secretary Clinton will not be traveling to California tomorrow or Tuesday," spokesman Nick Merrill said, hours after the 68-year-old candidate abruptly left the Ground Zero memorial suffering from what her doctor called dehydration.

Clinton, who has maintained a busy schedule over the past six weeks, particularly fundraising, is pausing on the campaign trail in the heat of a tightening race, and just two weeks before she and Republican rival Donald Trump square off in their high-pressure first presidential debate.
