Donald Trump has condemned attacks on the media after an incident involving a BBC cameraman at the US president's rally in Texas on Monday.
A White House statement did not refer to the specific incident.
It said the president "condemns all acts of violence against any individual or group of people - including members of the press".
The BBC's Ron Skeans was shoved and sworn at by a man in a Make America Great Again cap in El Paso.
The BBC later asked the White House to review security for media attending President Trump's rallies.
In a letter, the BBC said the press area was unsupervised, and no security had tried to intervene during the incident.
The White House statement, from Press Secretary Sarah Sanders, added: "We ask that anyone attending an event do so in a peaceful and respectful manner."
Mr Trump has been critical of media, which he has called the enemy of the people.
After Monday's incident, Mr Trump's campaign team thanked law enforcement for ejecting the unidentified man.
"An individual involved in a physical altercation with a news cameraman was removed from last night's rally," said Michael Glassner, the chief operating officer for Trump for President Inc.
"We appreciate the swift action from venue security and law enforcement officers."
