Thousands of protesters gathered in Chicago on the opening day of the Democratic National Convention (DNC) to voice opposition to the war in Gaza, with some breaking through a police fence near the convention site. Despite predictions of over 20,000 attendees, the turnout appeared lower than expected, with a few thousand participating in the initial rally. The protests, organized by the Coalition to March on the DNC, included a range of progressive issues but focused heavily on demanding a ceasefire in Gaza and ending U.S. aid to Israel. Chicago officials, including Mayor Brandon Johnson, emphasized their preparedness and commitment to maintaining peaceful demonstrations. Rolling street and expressway closures were implemented to manage the influx of protesters and dignitaries. The police reported no significant incidents during the initial protests, highlighting their efforts to protect both demonstrators' First Amendment rights and public safety.
