Washington — Vice President Kamala Harris is hitting the campaign trail with vice presidential running mate Minnesota Gov. Tim Walz in Philadelphia on Tuesday — the pair’s first rally together since she announced which Democratic candidate would be her VP pick hours ago.

The rally is scheduled to begin at 5:30 p.m. ET. 

In his first remarks as Harris’ running mate, Walz is expected to emphasize Midwestern values.

“Minnesota’s strength comes from our values — our commitment to working together, to seeing past our differences, to lending a helping hand,” Walz is expected to say, according to a Harris-Walz campaign official. 

And he’s also expected to go after Republican presidential nominee Donald Trump, saying that “he sees the world differently.”

“He doesn’t know the first thing about service because he’s too busy serving himself,” Walz is expected to say. 

With 19 electoral votes, Pennsylvania has the largest allocation among battleground states and a win in the state is likely to be pivotal to winning the White House in November. In 2016, former President Donald Trump unexpectedly won the state, which had voted for the Democratic presidential candidate since 1992. President Biden took it back in 2020.

Harris and Trump are tied at 50% among likely voters in Pennsylvania, according to the latest CBS News poll. The poll, which found Harris has a 1-point edge nationally, also shows the vice president and Trump in an even race in the other six battleground states. 

Trump’s running mate, Sen. JD Vance of Ohio, also made a campaign stop in Philadelphia earlier Tuesday. He plans to travel to other battleground states later this week, as well. 

Kamala Harris’ upcoming planned rally schedule

The Philadelphia rally kicks off Harris and Walz’s  cross-country tour in seven battleground states this week. The two will be campaigning in the following cities:

• Eau Claire, Wisconsin, on Wednesday
• Detroit, Michigan, on Thursday
• Phoenix, Arizona, on Friday
• Las Vegas, Nevada, on Saturday. 

Harris had also scheduled campaign stops in Raleigh, North Carolina, on Thursday and Savannah, Georgia, on Friday, but the events were postponed due to Tropical Storm Debby, which is forecasted to bring historic rainfall and flooding to southeastern states this week.
