(AP) - Democratic presidential candidate Hillary Clinton says she didn't think that her falling ill with pneumonia was going to be "that big of a deal."



Clinton tells CNN's "Anderson Cooper 360" that despite her doctor's orders to rest for five days, she thought she could "just keep going forward and power through it and that didn't work out so well."



Clinton's illness forced her to abruptly leave a 9/11 memorial ceremony in New York Sunday.
