The Democratic presidential candidate was meant to be hosting the event in Chapel Hill, North Carolina, on Tuesday but pulled out at the last minute with no explanation. Billed as "lunch with Hillary Rodham Clinton", tickets ranged from $100,000 for a "chair reception with Hillary" to $2,700 for a seat. The event was meant to take place at philanthropists' Betty Craven and Michael Warner's home.

Mr Trump rejoiced in the postponement, tweeting a sarcastic comment about her needing a rest. He tweeted: "Hillary Clinton is taking the day off again, she needs the rest. "Sleep well Hillary - see you at the debate!"

The tweet has been retweeted nearly 30,000 times and liked more than 65,000. Postponing the event has caused much speculation she is ill again after her campaign was forced to reveal she had pneumonia after almost collapsing at a 9/11 memorial event a week and a half ago. The speculation has risen to dizzying heights because North Carolina is a key battleground state where Mrs Clinton needs to drum up support.

Jason Husser, assistant professor of political scient and Elon, and director of the Elon University Poll, said: "This election is so tight right now, that small swings of a few points should be expected between now and November. “North Carolina has been extremely important over the last several election cycles with very tight election outcomes. “These numbers suggest that will continue to be the case, and both campaigns would do well to continue to focus on the Old North State.”
