Dramatic video from Donald Trump’s Radford, Virginia rally on Monday appears to show the moment a Secret Service agent allegedly grabbed a Time magazine photographer by the neck and threw him to the ground. Time’s Christopher Morris claimed he was grabbed by the agent after he stepped outside the designated “press pen” to take pictures of Black Lives Matter demonstrators as they were escorted from the event.

Another video from the rally is described as showing an exchange between the agent and Morris, moments before the incident. Credit: Instagram/cchorniak
