Hillary Clinton 'doing great' as she returns to campaign trail after pneumonia

US presidential candidate Hillary Clinton said she was “doing great” as she held her first rally after pneumonia forced her to take time out of the campaign trail.

The Democratic nominee, who will be going head to head with Donald Trump in the US election in just two months’ time, took three days off to recuperate.

Her health took centre stage after footage emerged of her appearing to nearly collapse at a 9/11 anniversary ceremony on Sunday.

But on Thursday Mrs Clinton walked on to the stage of a rally in Greensboro, North Carolina, to the sound of James Brown’s ‘I Feel Good’.

She called the time away at her home in Chappaqua, New York “a gift” which had allowed her to reflect on the campaign.

Just one day earlier, a note from Mrs Clinton’s doctor Lisa Bardack said she was “healthy and fit” and revealed bacterial pneumonia was the cause.

The 68-year-old told the crowd at the rally on Thursday: “"With just two months to go until Election Day, sitting at home was pretty much the last place I want to be."
