WATCH: Trump supporter goes berserk and attacks BBC cameraman at El Paso rally

A raving Trump supporter wearing a "Make America Great Again" hat attacked a BBC cameraman during the president's rally in El Paso.

BBC's Ron Skeans was recording video of President Donald Trump speaking about immigration when he was knocked off balance by a man in the crowd, who can be seen moments later being restrained by another man wearing a red MAGA hat.

The alleged assailant screams "f*ck the media" as he's pulled away from Skeans, and the crowd begins to chant "let him go" as they become aware of the disturbance.

Skeans later told the BBC that the man, who has not been identified, shoved him hard from his blind side, and the cameraman was not sure what had happened at first.

BBC Washington editor Eleanor Montague, who was at the event with Skeans, tweeted out footage of the incident, which she blamed on the president's hostile rhetoric.

“The crowd had been whipped up into a frenzy against the media by Trump and other speakers all night,” Montague tweeted.

A Trump campaign official later suggested the assailant was drunk, and Trump reportedly gave Skeans a thumbs-up signal, and then continued his speech after the cameraman returned the gesture.
