More violence at Trump events in Arizona

More violent confrontations occurred at Donald Trump’s rallies on Saturday, including a new incident Trump’s campaign manager who has been accused of assaulting a Brietbart News reporter.

A video shot at a Trump rally Saturday in Tucson, Ariz., shows Trump’s campaign manger Corey Lewandowski grabbing a protester by the collar and dragging him back through the crowd at Tuscon, Ariz., event. The protester then spins and pushes another man in the crowd.

Lewandowski made headlines after Breitbart News reporter Michelle Fields accused him of grabbing her at an event in Florida when she tried to ask the businessman a question.

The Trump campaign and Lewandowski denied he had grabbed Fields, while also attacking the reporter’s character. But Fields tweeted photos of finger-shaped bruises on her arm following the incident. The Trump campaign’s claims were further debunked by a Washington Post reporter who witnessed the incident and subsequently released video that shows Lewandowski reaching toward Fields.

Another video shot Saturday shows a Trump supporter brutally kicking and punching a protester before being escorted out by police.

Clashes between protesters and supporters of the GOP front-runner have turned violent, including earlier this month when Trump’s campaign cancelled an event in Chicago after violent confrontations between protesters and Trump backers.
