US presidential candidate Hillary Clinton has insisted she is “doing great” after a health scare.
However, following her recovery from pneumonia, the Democratic nominee faced a series of questions about her illness on her return to the campaign trail.
The 68-year-old former secretary of state said “sitting at home was pretty much the last place” she had wanted to be, but that the short break had allowed her to reflect on the campaign.

Speaking ahead of a rally in Greensboro, North Carolina, Mrs Clinton told media aboard her campaign plane: “Welcome back to ‘Stronger Together’. I am doing great, thank you very much.”
She later told supporters: “I tried to power through it but even I had to admit that maybe a few days of rest would do me good.
“I’m not great at taking it easy even under ordinary circumstances but with just two months to go until election day, sitting at home was pretty much the last place I wanted to be.
“But it turns out having a few days to myself was actually a gift.”
In allowing her time to think about the campaign, Mrs Clinton said: “People like me, we’re lucky.
“When I’m under the weather I can afford to take a few days off, millions of Americans can’t, they either go to work sick or they lose a paycheck don’t they.”
Earlier, US Secretary of State John Kerry told Sky News he is “absolutely convinced” Mrs Clinton is up to being president following her illness.
“I have no doubt about her physical stamina. She’s strong.”
The top diplomat said he was in “no doubt” about her physical stamina after she was forced to take three days off the campaign trail to recover.
Concerns were raised over Mrs Clinton’s health after she was was seen stumbling as she left a 9/11 memorial.
Her Republican rival Donald Trump has avoided directly referring to Mrs Clinton’s medical problems but has made a veiled attack on her health.
Earlier, Mr Kerry spoke to Sky News following the launch of his third summit on the world’s oceans and climate change.
He argued the oceans were “under siege” from a range of threats, including pollution and over-fishing.
“This is a life and death issue, as much as other challenges are a life and death issues,” he said.
Careful not to be drawn into the current battle for the White House, Mr Kerry would not directly comment on Mr Trump’s comments, in which he had questioned global warming and indicated he could ditch the global climate deal secured in Paris.
However, the veteran politician said he believed “very, very strongly” in the science of climate change and highlighted the series of measures taken by President Barack Obama to combat pollution.
He added: “I want that to continue in the future and I hope the American people will vote in a way that reflects the urgency of these issues.”
