Footage has emerged that shows a photographer covering a Donald Trump rally seemingly being pushed and shoved by a security guard.

Reports said that the photographer was "choke slammed" by the member of the security detail. It was not immediately clear whether the security guard was a member of the secret service or privately contracted.

According to eyewitness reports, the man was "credentialed press" and may been working for Time.

The incident took place at the rally at Radford University in Virginia. Reports said the event was interrupted several times by protesters.

Mr Trump has repeatedlty denounced the media and accused it of treating him unfairly. Last week, he said he wanted to introduce new libel laws that would limit press freedom.

"We're going to open up our libel laws so when [newspapers] write purposely negative stories … we can sue them and make lots of money," he said.

Last week, it was reported that some students planned to protest by bringing books and reading through the rally.

The university sent a note to students last week that read: "As an institution of higher education, we at Radford University must be tolerant of all viewpoints, even those with which we may not agree."
