Hillary Clinton had a rough start to her election rally on US Labour Day, battling a stubborn cough.
The Democratic nominee took to the stage in Cleveland coughing uncontrollably, before joking that, "every time I think about Trump I get allergic".
Several people in the crowd began shouting "get her some water".
She battled through the cough and delivered her speech with some difficulty.
Both Mrs Clinton and Donald Trump are in Ohio courting voters in the critical swing state.
