Fresh off a newly minted Democratic ticket, Vice President Kamala Harris and her running mate, Minnesota Gov. Tim Walz, are set to go on tour, hitting several battleground states in five days -- alongside them and mirroring their schedule state by state is Republican vice presidential nominee Sen. JD Vance.
On Monday, Harris introduced Walz to a fired-up crowd in Philadelphia; Vance was also in Pennsylvania on Monday. The candidates will campaign next in Wisconsin and Michigan.
Vice President Kamala Harris attended a fundraiser in San Francisco Sunday where she maintained her campaign "will win this election," but cautioned donors to "not take anything for granted."
"I know there's a lot of enthusiasm out there," Harris said, adding, "And you know, I've never been one to really believe in the polls -- whether they're up or they're down."
"What we know is the stakes are so high and we can take nothing for granted in this critical moment," she continued. "So we will fuel our campaign as we have, with enthusiasm and optimism, but also with a deep commitment to the hard work it’s going to take, and to campaign."
Speaker Emerita Nancy Pelosi introduced Harris at the event, touting the accomplishments of the Biden-Harris administration and the background of vice presidential nominee Tim Walz, several times calling the Harris-Walz ticket "the freedom ticket."
"[Harris] makes us all so proud. She brings us so much joy. She gives us so much hope," Pelosi said, calling the vice president "politically very astute."

In his first sit-down interview since stepping down from the 2024 race, President Joe Biden explained his historic decision.
"Look, polls we had showed that it was a neck-and-neck race, would have been down to the wire. But what happened was a number of my Democratic colleagues in the House and Senate thought that I was going to hurt them in their races," Biden said earlier this week in an interview with CBS News that aired on Sunday.
He also pointed to the fact that he always saw himself as a transitional figure, and he said that beating Donald Trump was "the most important thing" for him.
"Number two, when I ran the first time, I thought of myself as being a transition president. I can't even say how old I am, it's hard for me to get out of my mouth. And, but things got moving so quickly, it didn't happen. And the combination was that I thought it was a critical issue for me still, it's not a joke, maintaining this democracy. But I thought it was important because although it's a great honor being president, I think I have an obligation to the country to do the most important thing, and that is we must, we must, we must defeat Trump," Biden said.
"It's a danger -- he is genuine danger to American security,” Biden said. “Look, we're at an inflection point in world history of the decisions we make in the last three, four years, the next three, four years determine what the next six decades look like, and democracy is the key."

Vice President Kamala Harris spoke to reporters Saturday evening before boarding a flight from Phoenix to Las Vegas for a campaign event and discussed the latest incidents in the Israel-Gaza conflict.
She was asked about the Israeli Defense Forces strike on Al-Tabeen School in Gaza City, and said there are "far too many civilians who have been killed."
"Israel has a right to go after the terrorists that are Hamas. But as I have said many, many times, they also have, I believe, an important responsibility to avoid civilian casualties," Harris said.
When asked about the possibility the administration might set arms limitations on Israel, the vice president said it was important to have that a hostage deal and a cease-fire.
"And I can't stress that strongly enough, it needs to get done. The deal needs to get done, and it needs to get done now," she said.

Former President Donald Trump's campaign is claiming it was hacked by "foreign sources" with the intent to interfere in the upcoming election.
The Trump campaign statement cited a report published by Microsoft on Friday, which said, "In June 2024, Mint Sandstorm—a group run by the Islamic Revolutionary Guard Corps (IRGC) intelligence unit—sent a spear-phishing email to a high-ranking official of a presidential campaign from a compromised email account of a former senior advisor. The phishing email contained a fake forward with a hyperlink that directs traffic through an actor-controlled domain before redirecting to the listed domain."
Microsoft does not identify the presidential campaign in its report. Microsoft has also not responded to ABC's request for more information.
Outside of the Trump campaign statement, ABC News has not confirmed the campaign was hacked by foreign sources with the intent to interfere in the election.
Vice President Kamala Harris and Gov. Tim Walz dropped by the North Phoenix coordinated campaign office on Friday to meet with volunteers making signs.
"Aw, Momala," Harris said reading a sign that made mention of her step kids' nickname for her.
The vice president laughed when she saw on person's "Coconut > Orange" sign.
"We just wanted to stop by to say thanks, guys," she said.
The duo took a selfie in front of a large "Kamala and Coach" sign at the end.
They then invited those in attendance to join them in the motorcade to the rally.
On the tarmac, a reporter asked Walz if he had spoken with Sen. JD Vance. He did not answer.

Former Vice President Mike Pence reiterated Friday that he would not vote for his successor despite not supporting former President Donald Trump.
"Let me go on the record here at the gathering: I could never vote for Kamala Harris as president of the United States, or Tim Walz, as her running mate. Period," Pence said during an on-camera interview with conservative radio host Erick Erickson.
Pence defended his decision to not support Trump, citing several issues including "marginalizing the right-to-life in our party, as we saw on the national platform."
"I cannot endorse President Trump's continuing assertion that I should have set aside my oath to support and defend the Constitution and acted in a way that would have overturned the election in January of 2021," Pence added.
The former vice president did say he was grateful that Trump was not seriously hurt during the attempted assassination during a rally in Pennsylvania last month.
"Karen and I, we were in a plane, we had just landed, and I had got a text from someone watching it in real time. It took my breath away," he said, referring to his wife. "I truly admired the way the president stood up and raised his fist and walked off that stage."

President Biden and Vice President Harris will hold a joint event in Maryland on Thursday, Aug. 15, according to the White House.
They will discuss "the progress they are making to lower costs for the American people," the White House said.
Meanwhile, ahead of visits this weekend to Arizona and Nevada, the Harris campaign is touting what it called its "historic ground game advantage" in the two battleground states.
In a memo, the campaign also notes the elevated importance in Arizona and Nevada of reproductive freedom, as abortion-related ballot measures will be in place in each state this fall.
"Vice President Kamala Harris and Governor Tim Walz's momentum across the battlegrounds is real and will be on full display in Arizona and Nevada, where we've built massive coordinated campaigns as Trump has almost no presence whatsoever," the memo read. "Our campaign will continue our work to reach the diverse voters who power our victories in the Southwest, highlighting the stakes of the race for reproductive rights and the Vice President's leadership to secure the border."
Former President Donald Trump is set to hold a campaign rally in Bozeman, Montana, on Friday.
Vice President Kamala Harris will not be joining former President Donald Trump on Fox News' debate stage on Sept. 4, a Harris campaign official told ABC News.
The official said Harris agreeing to future debates is contingent on Trump showing up and "keeping his word" to the Sept. 10 debate, hosted by ABC News.
Harris' campaign is willing to have conversations about future debates, but they must be scheduled after Sept. 10, according to the official.
Vice President Kamala Harris and Gov. Tim Walz gave remarks at a local United Auto Workers office in Wayne, Michigan, on Thursday, championing "the collective."
Walz praised Harris' leadership, saying, "She stands on the side of the American people and the American worker. She’s the one who took on the predators, the fraudsters, the transnational gangs," Walz said.
"And she’s the one that stands up against the billionaires and the corporate greed -- it’s who Kamala Harris is," he added.
Harris took the stage largely repeating her newly tested stump speech, letting the audience know her campaign is for everyone.
"We believe in the collective," Harris said. "We're not falling for these folks who are trying to divide us trying to separate us, trying to pull us apart. That's not where the strength lies," she added.
She ended her remarks by reminding the crowd of how many days were left until voting day and how much hard work was left to win the election.
"We've got 89 days to get this done. You know, the one thing about all of us is we like hard work. Hard work is good work," she said.
