Český hasič zasáhl do prezidentské volební kampaně v USA

An unverified video of the episode appeared to show Clinton collapsing as she was helped into the van.

The New Jersey resident who took the video, Zdenek Gazda, told Foxnews.com he had been a fireman in the Czech Republic and came to the 9/11 ceremony to pay his respects.

"Everything was fine, everything was good before," said Gazda, who snapped several shots of Clinton before taking the video. "I take a lot of pictures of her. She looked very nice and everything, and I don’t know what happened to her."
