GOP presidential frontrunner Donald Trump's campaign rally has been shut down and postponed over "safety" concerns.
Thousands of supporters and protesters showed up at UIC Pavilion for the event and legislative leaders, including U.S. Rep. Luis Gutierrez and Chicago 15th Ward Ald. Raymond Lopez, both of whom spoke ahead of the rally.

Emotions are high, with fist fights breaking out inside the UIC Pavilion this evening and Trump supporters sending Progress Illinois controversial messages on social media as we live tweet from the protest and rally.
Trump supporters are also upset saying that the disruption of Trump's event from protesters is a violation of First Amendment rights.
UPDATE 1: The Chicago rally was canceled by the Trump campaign.
When the event was canceled, a Trump campaign rep came onstage stating: "Mr. Trump just arrived in Chicago and, after meeting with law enforcement, has determined that for the safety of all the tens of thousands of people that have gathered in and around the arena, tonight's rally will be postponed until another day. Thank you very much for your attendance and please go in peace."
The Chicago police reps told the Associated Press that they did not tell the Trump campaign that there was a security threat, nor did they advise that the event be canceled. CPD said they had sufficient force on the scene to address any issues that may have occurred. UIC police also say they did not encourage Trump to cancel the rally.
