Hillary Clinton was reportedly caught on video trying to

It has been nearly a week since Hillary Clinton's campaign revealed that she had been diagnosed with pneumonia, following a 'medical episode' during the 9/11 memorial ceremony.

And now, as she hits the campaign trail, it seems that she still isn't well.

The Democratic presidential nominee was coming to the end of her 20-minute speech to the Black Women's Agenda Workshop in Washington, DC, on Friday, when she let a couple of coughs slip, The American Mirror reported.

But the hot mic picked the cough up. Clinton could also be seen coughing again and covering her mouth as she exited the stage

During the last minute of her speech Clinton said she wouldn't have run for president again if 'I did not in my heart believe with every fiber in my being, that together we can build a future where yes, love trumps hate'.

She then thanked a cheering crowd while she stood in front of the podium and waved.

The 68-year-old then appeared to try and hide her coughs by not covering her mouth and standing still, but the hot mic picked it up.

Within the past week, Clinton's collapse has added to the growing fears for her health, which began mounting on Labor Day when she broke out in a coughing fit during a speech in Ohio.

Her rival, Donald Trump, suggested that Clinton has been sick for awhile, pointing to her coughing fit as evidence that 'something's going on'.

During the 9/11 'medical episode, Clinton's campaign blamed 'overheating' but later revealed that she had been diagnosed with pneumonia

'I really just don't just know. I hope she gets well soon. I don't know what's going on,' Trump said when asked about it on 'Fox and Friends' Monday morning.

He wished Clinton well after her health scare during the 9/11 memorial ceremony.

Trump was uncharacteristically silent – including on Twitter – last Sunday, even as Clinton was spirited away from the ceremony in New York, where she was captured on video stumbling on the way to her van.

Her campaign had earlier blamed 'overheating' for the episode - which saw her rushed away from the ceremony at Ground Zero and back to Chelsea's apartment.

But campaign officials finally revealed she had been diagnosed with pneumonia.

Clinton's doctor said she was put on antibiotics, and advised to rest and modify her schedule following the incident.

She had been scheduled to attend fundraisers on Monday and Tuesday in California, and tape an episode of Ellen DeGeneres' talk show, following the ceremony.
