DNC 2024 Day 2: 'Yes, she can': Obama endorses Harris, blasts Trump

As he did on Monday, Trump and his running mate, Ohio Sen. JD Vance, are continuing on their separate trips across battleground states to keep Democrats from having the political spotlight all to themselves.

Trump heads to Howell, Michigan, for a crime and safety event, while Vance hosts something similar in Kenosha, Wisconsin. As they did Monday, Trump's campaign and surrogates - including Rep. Byron Donalds of Florida - plan a media briefing on the sidelines of the DNC in Chicago, with the daily theme of "Make America Safe Again."

JD Vance will host a crime and safety event on Tuesday in Wisconsin.

Tuesday morning, crews appeared to be adding additional fencing where the area was breached, with a second line of fencing behind the original barriers.

Just as delegates were arriving here at the United Center Monday, some protesters breached the outer security fence.

Video shows whole sections of snap-together iron fencing taken down and in some cases dragged away by protesters.

According to convention organizers, the theme for Tuesday's events is "A bold vision for America's future," a defined pivot toward a new generation for Democrats and their leadership. After a Monday night that flicked at Harris' possibility but also lauded the legacy of Biden and his decades of accomplishment, convention organizers now appear ready to shift toward the next stage of their journey.

In laying out their plans for the week, convention organizers described Tuesday night as a way to contrast what they characterized as Harris' forward-looking strategy with Trump's less positive outlook on America's future.

As they did on Monday, Democrats also plan to showcase "everyday Americans" and some performers during each night, in addition to the elected officials and party leaders.

Former President Barack Obama and former first lady Michelle Obama are returning to the city they once called home to take the stage in support of Harris' nomination.

The Obamas are expected to headline the convention's second night, a day after the unofficial farewell for Biden, who served eight years as Obama's vice president. Biden won't be in the hall to see his former running mate speak, having departed Chicago after his own speech.

According to the Harris campaign, Michelle Obama is expected to argue how Harris' experiences and values make her qualified to serve as president. Her husband, Harris campaign officials said, will focus on what Democrats need to do in order to defeat Trump in the general election.

In addition to the Obamas, Harris' husband, second gentleman Doug Emhoff, is also scheduled to give his speech on Tuesday night. Emhoff, the nation's first second gentleman, would also be the first man to be first gentleman if Harris is elected president.

Also on the schedule is Illinois Gov. JB Pritzker, a potential future presidential hopeful whose name for a time was mentioned as a possible running mate for Harris.
