Clinton 'anxious to get back out there' on campaign trail after 'collapsing' at 9/11 memorial event

Hillary Clinton's spokesman said the presidential candidate will likely be back on the campaign trail later this week.

Clinton was diagnosed with pneumonia before her apparent 'fainting' at a 9/11 memorial service.

An unverified video purportedly taken at the event appeared to show Clinton collapsing as she prepared to leave.

Tonight Clinton tweeted she is "anxious" to get back on the campaign trail:

Her spokesman said she never lost consciousness during the episode and was "alert the whole time" in the car after departing the memorial event.

The spokesman said the campaign made "immediate attempts" to get in touch with Clinton's physician after the incident.

He added the doctor has stated there is no correlation between the 2012 health episode and the recent incident.

Donald Trump's team and his supporters have repeatedly made unsubstantiated claims that she has health issues and is physically incapable of being president.

The campaign will be releasing additional medical information, he added.
