CHICAGO (AP) Vice presidential nominee Tim Walz and former President Bill Clinton are headlining the Democratic National Conventions third day on Wednesday, as the party hopes to build on the momentum that Kamala Harris has brought since joining the race a month ago.

Walz, the Minnesota governor who has become known among supporters as a folksy, Midwestern teacher, football coach and dad, will introduce himself to the rest of the country. Hes also become the target of Republican criticism over how hes portrayed his National Guard service and his personal story.

Organizers have dubbed Wednesday night a fight for our freedoms, with the programming expected to focus on abortion access and other rights that Democrats want to center in their campaign against Republican nominee Donald Trump . Transportation Secretary Pete Buttigieg, former House Speaker Nancy Pelosi and House Minority Leader Hakeem Jeffries will speak along with everyday Americans whom convention organizers describe as people who will argue their freedoms hinge on the result of the upcoming election.

Mini Timmaraju, president of the national reproductive rights group Reproductive Freedom for All, highlighted states including Florida, Arizona and Montana that will have voter referendums in November on protecting abortion access at a state level.

The people will get to have their say this November, she said.

Also expected onstage are music icon Stevie Wonder and legendary talk show host Oprah Winfrey, who gave a critical endorsement of then-Sen. Barack Obama in the 2008 presidential election. Country music star Maren Morris and poet Amanda Gorman were also performing and an appearance by comedian Kenan Thompson was planned.

Clinton is the nations 42nd president and a veteran of his partys political convention going back decades .

In 2024, we have a clear choice: We The People versus Me, Myself, and I, Clinton plans to say, according to early excerpts of his address. He will also say that Kamala Harris is the only candidate in this race with the vision, the experience, the temperament, the will and yes the sheer joy to do that on good and bad days. To be our voice.

Wednesdays program also includes two governors, Wes Moore of Maryland and Josh Shapiro of Pennsylvania, and several Democratic senators: Cory Booker of New Jersey, Chris Murphy of Connecticut, Catherine Cortez Masto of Nevada and Amy Klobuchar of Minnesota.

Democrats are trying to demonstrate that they have a large number of future potential contenders beyond Harris, and that includes others who have gotten huge cheers while appearing throughout the week at the convention, like Michigan Gov. Gretchen Whitmer.

Coach Walz takes the stage

Many Americans had never heard of Walz until Harris chose him to join her ticket. In his first weeks of campaigning, hes charmed supporters with his background as a teacher and football coach and helped to balance Harris coastal background as a cultural representative of Midwestern states whose voters she needs this fall.

But Walz also has faced scrutiny, including questions about embellishing his background. His wife this week clarified that she did not undergo in vitro fertilization , as Walz has repeatedly claimed, but used other fertility treatments. Republicans also have criticized Walz for a 2018 comment he made about carrying weapons in war. Though he served in the National Guard for 24 years, he did not deploy to a war zone.

Still, polling data shows that despite early hiccups, Walz has had a smoother launch as Harris running mate than Republican JD Vance, Trumps pick for vice president.
