The man who filmed Hillary Clinton collapsing after attending a 9/11 memorial is being lauded as a 'hero' by Trump supporters.

Zdenek Gazda, a firefighter from the Czech Republic who now lives in New Jersey, was a special guest at the Deplora Ball after the inauguration on Friday.

A host of the event introduced Gazda as a 'hero' and 'the man who turned the election around'.

In an interview with Cosmopolitan, Gazda said he got the video by accident.

He was at the 9/11 memorial on the anniversary of the attacks, as he is every year to honor the fallen, when he saw Clinton and her entourage passing.

He got out his camera to record the presidential candidate and caught the moment her security guards had to catch her as she feinted.

Gazda immediately posted the video, and Clinton was eventually forced to admit that she was being treated to pneumonia - raising questions among some about whether she was fit to lead.

Gazda, a Trump supporter, says he has no regrets about the video.

'I put it on Twitter immediately,' Zdenek said. 'I don't like [Hillary] because she lied. She's sick ... I was scared too because so many people like her. But I closed the door on her for the White House. A lot of people say with a 20-second video, I changed the history of the United States.'

Gazda also revealed that he 'tried' to make money off the video, and was successful by selling it to Storyful. He did not say for how much.
