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

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."

Former Trump adviser Peter Navarro will speak at the RNC tonight just hours after being released from federal prison in Miami this morning, according to a source familiar with the situation.

Navarro's release date for serving time after being convicted on contempt of Congress charges was previously set for today, and according to a source, he left prison this morning.

He served four months in a low-security facility.

Donald Trump's running mate – the 39-year-old first-term senator from Ohio – gets his chance in the national spotlight when he makes a prime-time speech at the RNC.

J.D. Vance can be expected to tell his personal story of growing up in Middletown, Ohio, and the upbringing that inspired him to write his best-seller "Hillbilly Elegy."

Even with that, he is largely an unfamiliar face to many Americans – even to Republicans – including those in the convention hall.

Trump can again be expected to be watching from his presidential box.

Vance will be introduced by his wife, Usha Chilukuri Vance, after strong Vance- backer Donald Trump Jr. speaks right before.
