A supporter of President Trump attacked a BBC camera operator during a presidential rally in El Paso on Monday night, the broadcaster said.

“BBC cameraman Ron Skeans was violently pushed and shoved by a member of the crowd while covering a President Trump rally in Texas last night,” a BBC spokesman said in an email on Tuesday.

Mr. Trump was in El Paso to increase support for his proposed wall on the United States border with Mexico, in his most significant rally since his funding demands for the project temporarily shut down the government. The president was talking about a decline in attacks on African, Hispanic, and Asian-Americans when the cameraman was pushed.

A 36-second clip from Mr. Skeans’s camera before, during and after the shove was widely circulated on social media on Tuesday. It shows a protester in a red Make America Great Again cap, who has not been publicly identified, shouting at members of the media as he is restrained by someone who appears to be part of the event’s security team.
