Many different activist groups converged for a march to the venue where they began to link hands to block the roadway. Protesters were both inside and outside the building, and many of them appeared to be UIC students.
Anyone who was wearing anti-Trump clothing or carrying protest signs were not allowed into the event, however, many demonstrators made their way inside and were met with a hostile crowd.

After the announcement that the event was cancelled, fights broke out both inside and outside the venue. A demonstrator also made his way to Trump's podium.

CBS Chicago station WBBM reported that a Chicago police officer was injured during the clashes. CBS said its news reporter Sopan Deb was detained by law enforcement while covering the protest.
Earlier in the day, as Trump spoke in St. Louis, a black Ferguson activist was beaten and bloodied by one of the candidate's supporters as he used a bullhorn to denounce racism. Videos uploaded to social media also showed Trump's followers shouting hate speech at the protesters, unsurprisingly, as Trump himself seemed to encourage violence from the podium. After being interrupted, the presidential hopeful lamented that it was a “shame” that protesters had to be treated “gently” by police.
