RADFORD, Va. » A Secret Service agent and a news media photographer got into a verbal and physical altercation at a raucous Donald Trump presidential campaign rally riddled with protests today in Virginia.

Chad Morris, the photographer, was escorted out of the tense rally and detained before being released. The Secret Service says it is investigating “the exact circumstances.” The agent has not been identified.

Videos of the incident taken by reporters and attendees show Morris attempting to secure a better position to photograph some of the many protesters who were kicked out of Trump’s event. Rebuffed by the agent, Morris curses at the man, who then grabs Morris and takes him to the ground.

Seconds later, Morris touched the agent to demonstrate his version of what happened. He was then escorted out.
