Harris, Walz to make first joint campaign appearance in Philadelphia

Vice President Kamala Harris and her newly announced presidential running mate, Minnesota Gov. Tim Walz, are slated to make their first campaign appearance together on Tuesday evening in Philadelphia, before a large crowd.

Hundreds of supporters were waiting in lines outside the Liacouras Center at Temple University for the event, which is scheduled for 5:30 p.m. ET.

Walz and Harris are expected to highlight their contrasts to former president Donald Trump and Sen. JD Vance.

Walz will tout Harris' experience as a prosecutor, senator and vice president during his speech, according to excerpts that were released prior to the event.

"She took on predators and fraudsters, took down transnational gangs, stood up against powerful corporate interests, she's never hesitated to reach across the aisle if it meant improving people’s lives. And -- she brings joy to everything she does," the excepts read.

The governor will also speak about his history from his days as a teacher to legislating as an elected official.

"These same values I learned on the family farm and tried to instill in my students, I took to Congress and the state capital, and now, Vice President Harris and I are running to take them to the White House." the excerpts read.

"Donald Trump -- he sees the world differently. He doesn’t know the first thing about service -- because he's too busy serving himself," the excerpts read.

Vance held a rally in the Philadephia area earlier in the day.

Tuesday's Harris-Walz event kicks off a five-day campaign road trip that will visit seven crucial swing states.

The vice president and Walz are scheduled to visit Eau Claire, Wisconsin; Detroit, Michigan; Durham, North Carolina; Savannah, Georgia; Phoenix, Arizona; and Las Vegas this week.
