DNC Day 1: President Biden says 'America is winning' and Trump is a 'loser'

Democratic National Committee delegates passed the party's 2024 platform in a voice vote.

A full, 92-page draft platform was unveiled by the party late on Sunday night. The document, which was written before President Joe Biden left the 2024 race, was voted upon by the DNC's Rules Committee in July. It was not updated significantly since Harris replaced him at the top of the ticket.

"USA" chants broke out in the stadium after the platform was adopted.

The Rev. Jesse Jackson, the civil rights leader and 1988 Democratic presidential candidate, received a standing ovation when he was wheeled on stage, right after a video on the civil rights movement ended.

Jackson was joined by other civil rights icons, including the Rev. Al Sharpton.

U.S. Rep. Jonathan Jackson spoke with ABC7 Chicago ahead of his father, civil rights activist Rev. Jesse Jackson, being honored on the first night of the 2024 DNC.

The first night of the DNC is underway in Chicago, with the convention officially called to order.

Tonight's theme is "For the people" and the evening is being hosted by actor Tony Goldwyn -- who famously played a president on TV in the ABC series "Scandal."

Chicago Mayor Brandon Johnson welcomed delegates to the 2024 DNC with a rousing speech.

Four people were arrested after protestors breached the security fencing on the north side of the United Center, CPD Superintendent Larry Snelling said.
