Watch Live: Violence Erupts as Donald Trump Postpones Chicago Rally (Video)

Thousands of protesters celebrate their success at keeping the GOP presidential frontrunner from speaking

Donald Trump was forced to cancel a rally in Chicago due to security concerns.

The Associated Press is reporting that protesters are celebrating their success at keeping the GOP presidential frontrunner from taking the stage. According to the AP,  Trump supporters walked through the anti-Trump crowd outside the University of Illinois-Chicago Pavilion this afternoon, chanting, “We stopped Trump! We stopped Trump!”

According to the local NBC station in Chicago, scuffles broke out in the crowd. Some people could be seen yelling at each other or making vulgar gestures and at least one punch was thrown. A man who stormed the podium was forcibly escorted away by police officers.

The local ABC station reports Chicago police had to enter the building to help control crowds, with many of  them appearing to be University of Illinois at Chicago students.

In a statement shortly after the rally was canceled, Trump’s campaign sent out a statement saying: “Mr. Trump just arrived in Chicago and after meeting with law enforcement has determined that for the safety of all of the tens of thousands of people that have gathered in and around the arena, tonight’s rally will be postponed to another date. Thank you very much for your attendance and please go in peace. ”
