KTLA reporter Steve Kuzj was doing a live report from Hollywood, California, on Wednesday night about the recent measles outbreak when a passerby tried to get in his shot and yell.
Without missing a beat, Kuzj pushed the unidentified man away, noted TMZ (video below).
The man continued to talk off-camera, but was unintelligible.
Kuzj, who reportedly has martial arts background, later tweeted, "To be clear, that was a crazy man running at me, swearing, trying to get on TV. I was defending myself and viewers from hearing obscenities."
