Minnesota Gov. Tim Walz is set to deliver his first speech as the newly minted running mate of Vice President Kamala Harris at a rally in Philadelphia on Tuesday evening.

"I couldn't be prouder to be on this ticket, and to help make Kamala Harris the next President of the United States," Walz is planning to say, according to excerpts of his speech. "She brings joy to everything she does."

Walz will also mention his Midwest background, which Democrats see as an advantage for the ticket, potentially having an appeal to rural voters.

"I was born in West Point, Nebraska and lived in Butte, a small town of 400 where community was a way of life," Walz will say. "Growing up, I spent summers working on the family farm. My mom and dad taught us to show generosity toward your neighbors and to work for the common good."  

The Pennsylvania rally is the first joint public appearance of the new Harris-Walz ticket, which the campaign officially announced Tuesday morning.

In the hours since, the campaign has released new Harris-Walz merchandise, several advertisements introducing the new name on the ticket and social media
