The attack, which targeted a number of news crews in the press corps at the Trump rally, appeared to leave the British cameraman, Ron Skeans, taking the brunt of the violence.
Mere minutes later, Trump brought attention to the press in the room, jeering at them and eliciting boos from the crowd.
He has claimed journalists are "the enemy of the people" and slammed the "fake news" for reports he deems unfavourable. "Everything OK?" He gave Skeans the thumbs up and the cameraman signaled that he was OK, the BBC reported.
He said a supporter of Mr Trump got onto the reporters' platform, and pushed the camera into his colleague, before continuing to push Mr Skeans.
The BBC's Washington correspondent Gary O'Donoghue described Monday's incident as "an incredibly violent attack" in an interview with his employer. "Fortunately our cameraman is fine, he is made of stern stuff", he told BBC Radio 4's Today programme.
Skeans recovered to film a man in a red "Make America Great Again" cap being restrained and shouting: "Fuck the media".
Mr Trump's "Finish the Wall" rally in El Paso was the first dueling rallies of the 2020 campaign season.
Mr O'Donoghue said the goading of the crowds against the media is a "constant feature of these rallies".
'I have been spat at before, they hurl abuse at American colleagues in particular'.
'The man was removed by security and Ron is fine.
Mitt Romney, a senator from Utah and former Republican presidential nominee, argued a year ago that Trump's tactics are detrimental to democracy.
"The crowd had been whipped up into a frenzy against the media by Trump and other speakers all night", Montague tweeted.
