However, BBC Washington Editor Eleanor Montague, whom he was with, told BBC the protester had attacked other crews within the rally but Skean "got the brunt of it".
As the footage shows, Skeans was recording Trumps speech when the footage suddenly stumbles forwards as he is hit.
Describing what unfolded, he said a supporter of Mr Trump got on to the reporters' platform and pushed the camera into his colleague, before continuing to push Mr Skeans.
Trump, who noticed the altercation, checked whether Skeans was alright by giving him a thumbs-up.
A campaign official for Mr Trump later suggested the attacker was drunk, according to BBC News. "The man was removed by security and Ron is fine", the statement read.

"After going through this whole year these last 24 months of my life have been a roller coaster", Edelman said. This is what I sacrificed all my time for - my friends, my family, everything like that", Edelman explained.
The BBC's Washington correspondent Gary O'Donoghue, who is blind, tweeted a clip of the assault and said such behaviour was a "constant feature" of Trump rallies.
In freewheeling remarks at his rally, Trump also trashed the 'Green New Deal, ' but didn't single out its most prominent backer, Rep. Alexandria Ocasio-Cortez - although he bashed Democrats generally. "Fortunately our cameraman is fine, he is made of stern stuff", he told the Today programme.
"I have been spat at before, they hurl abuse at American colleagues in particular".
Trump's rally in El Paso was also his first direct clash with potential 2020 presidential rival Beto O'Rourke.
As President Trump talked about the current unemployment rate among minority groups in America, a man wearing a MAGA hat allegedly shoved a BBC cameraman, knocking both him and his camera over.
Mr O'Rourke, meanwhile, held a countermarch with dozens of local civic, human rights and Hispanic groups in his hometown, followed by a protest rally attended by thousands on a baseball field within shouting distance from the arena where Mr Trump spoke. We don't even say build the wall anymore.
