RNC 2024 Day 3 updates: JD Vance touts working class roots in debut as VP nominee

Kai Trump, the daughter of Donald Trump Jr. and granddaughter of former President Donald Trump, is scheduled to speak at the Republican National Convention Wednesday night at 9 p.m. CT/10 p.m. ET, she posted on her social media account.

"I am honored to be speaking at the RNC at 9 pm (CDT)," she posted with a photo of the former president and Sen. J.D. Vance.

Kai Trump, the 17-year-old daughter of Donald Trump Jr. and his ex-wife Vanessa Trump, is the eldest of Trump's 10 grandchildren.

Over the weekend, she posted a photo of the former president pumping his fist after being shot at his Pennsylvania campaign rally, writing: "We love you Grandpa. Never stop fighting!"

In June, she posted a photo of herself with Donald Trump at what appears to be a Turning Point Action event in Detroit, Michigan.

Sen. J.D. Vance is scheduled to hold his first fundraiser as former President Donald Trump's running mate Wednesday afternoon, sources familiar with the event told ABC News.

And Trump and Vance are scheduled to hold a roundtable-style fundraiser together Thursday afternoon, sources said.

This isn't Vance's first time fundraising alongside Trump. As then-possible vice presidential contender, Vance had joined the former president on multiple Trump campaign fundraisers -- including hosting fundraisers in Ohio and attending other fundraisers at a special guest speaker.

Trump will attend the RNC events Wednesday evening -- as he has the previous two days.

The former president is expected to enter the arena around the same time as Tuesday night -- around 8:02 p.m. CT.

The last two days, Trump, with a bandaged ear, has entered Fiserv Forum to cheers from his supporters and chants of "fight, fight, fight" as he pumps his fist in the air -- a callback to his response shortly after an assassination attempt on him at his rally in Pennsylvania on Saturday.

It had been less than 48 hours since the attempted assassination attempt against former President Donald Trump, and for four Wisconsin voters, it was yet another sign of how divided the nation has become.

Valori Schmidt, a Republican living in Milwaukee, described the shooting at the former president's Pennsylvania rally as a "wake-up call."

"Unfortunately, it wasn't necessarily a surprise because the climate of hatred has escalated to such a high level," Schmidt said. "The wake up call is we must take the temperature down. We must become more civil, and we must start being factual and not not name calling and just saying awful things about one another."

Next to her, Gary Berns, a fellow Milwaukeean who votes Democratic, replied: "I can't disagree with that."

Berns and Schmidt, joined by other local residents Julie Buckholt and Charlene Abughrin, sat down with ABC News at Miss Katie's Diner just as the Republican National Convention was kicking off in their hometown.

"As far as the loudness and the anger calling, I mean he brings that on himself," Berns said of Trump. Schmidt later countered that Trump, "has been vilified as a Hitler, as an anti-American, as an extremist … it's been nonstop from all aspects."
