Democratic presidential nominee Hillary Clinton on Monday gave her first public interview since she was abruptly removed from a 9/11 memorial event in Manhattan on Sunday after suffering what senior law enforcement officials described as a “medical episode.”

In the interview with CNN, quoted by Reuters, Clinton said she could resume campaigning in a "couple of days" after a bout of pneumonia which caused her to nearly collapse at Sunday's event and cancel some of her trips.

"I'm feeling so much better and obviously I should have gotten some rest sooner," she said, admitting she had ignored doctor's orders to rest.

"Well, it will be in the next couple of days. ... I just want to get this over and done with and get back on the trail as soon as possible," she said of her campaign plans.

Clinton, 68, said she had had similar episodes before. "I think really only twice that I can recall. You know, it is something that has occurred a few times over the course of my life. I'm aware of it and usually can avoid it."

Clinton's doctor had said after Sunday's incident that she was suffering from pneumonia and the incident at the memorial was a result of dehydration and overheating.

The Clinton campaign has come under fire for saying originally that Clinton was just “overheated” and not revealing until later she had been diagnosed with pneumonia the prior Friday.

Earlier on Monday, Clinton's campaign acknowledged that it mishandled her health scare and promised to release additional medical details in the coming days.

Both Clinton and Republican rival Donald Trump, 70, said they intended to release more of their medical details in the coming days, as their campaigns gear up for the November 8 election.
