A video is circulating purportedly showing Donald Trump’s campaign manager, Corey Lewandowski, grabbing the collar of a protester at a Trump rally in Tucson, Arizona. 

Trump’s campaign stops have become the target of violent disruption in recent weeks. On March 19, protesters chained themselves to cars to block a highway to prevent Trump supporters from attending the event in Arizona. 

Earlier this month, protesters in Chicago forced Trump to cancel a rally there after violence broke out between the anti-Trump protesters and the rally attendees. 

Lewandowski had been previously accused of grabbing the arm of Breitbart reporter Michelle Fields and leaving a bruise on her arm.
