RADFORD, VA. — A Donald Trump rally in southwest Virginia on the eve of Super Tuesday turned nasty, with repeated disruptions by protesters, and a scuffle between a Secret Service agent and a photographer.



Trump addressed a crowd of thousands in a Radford University gymnasium, as many more waited outside. The Republican front-runner started his remarks by citing a new CNN poll showing him with a huge national lead. The New York billionaire is poised to win many of the states voting on Tuesday and has led the polls in Virginia. He said he's positioned to win states that historically back Democrats, including New York and Michigan.



As Trump spoke, he lamented interruptions to his message about how he'd keep jobs in the United States.



Trump was describing how he would react to companies like Carrier moving air conditioner production to Mexico when he was interrupted by commotion in nearby bleachers. The crowd was jeering at an apparent protester.



"Are you from Mexico?" he repeatedly shouted at the woman as she stepped down from the bleachers.



On the other side of the room, three rows of young people, mostly African-Americans, stood up, holding hands and shouting, "No more hate." It took nearly 10 minutes to escort them out of the room as supporters jeered, and Trump shouted to get the protesters out.



"All lives matter," Trump shouted as they left to loud cheers, mirroring similar comments made Sunday in Alabama.



Shortly after, Christopher Morris, a photographer for Time magazine, was attempting to leave the press section to photograph the Black Lives Matter protesters when he was "thrown to the ground in a choke hold," Time said, by a Secret Service agent.



Morris later told reporters that he "never touched" the agent. Video shows that after Morris was thrown to the ground by the agent, he kicked at the officer who was trying to restrain him. Video also shows Morris reaching for the officer's neck, which Morris says was to demonstrate what the officer had done to him. Time said Morris was briefly detained.
