Hillary Clinton reportedly caused a scene at a 9/11 memorial ceremony held in New York on Sunday.

The Democratic presidential nominee fell on her way into her van and had to be helped by her security, according to witnesses and video of her leaving. She was “clearly having some type of medical episode," a law enforcement source told Fox News.

She was then taken to her daughter’s home nearby and emerged a few hours later to debunk rumors of ill health.

Clinton's doctor has said the episode was a result of heat and dehydration and revealed she had been diagnosed with pneumonia two days prior.
