Gov. Tim Walz delivered remarks at a "Native Americans for Harris-Walz" get-out-the-early-vote rally in Window Rock, Arizona, on Saturday afternoon– a remote location on the Navajo Nation.

Walz's visit marks the first time a candidate on the presidential ticket has gone to Navajo Nation this cycle, according to the campaign.

"We're here because we're not taking any vote for granted, and we're here to show respect to the Navajo Nation and earn your vote. Now I'll tell you we're running like everything's on the line, because everything's on the line," he said.

Walz said that given the closeness of this election, especially in the battleground state of Arizona, Native votes may really tip the scales for the Democratic ticket.

"I think, probably, that we win the whole damn thing because of the work that was done here, the work that's done on the nation, and we put Kamala Harris in the White House," Walz said.

Walz claimed that Donald Trump did not give Native Americans support in office and specifically blasted Trump for his gathering with families of Navajo war veterans at the White House in 2017.

The event occurred in front of an image of Andrew Jackson, the president who signed legislation that eventually led to the "Trail of Tears."

"I don't know if he knows his history well enough to know what he was doing, but I damn sure guarantee you the people around him knew the insult they were throwing to Indian country by making those heroes stand in front of that portrait," Walz said.

Walz highlighted how his and Harris’ economic policies would boost Tribal entrepreneurs and businesses and better their health care options.

"I want to be clear and make sure you hear it and that the country hears it. Kamala Harris and I recognize the promises this country has been made to indigenous peoples. We will safeguard and strengthen the bonds between our nations and uphold our trust and treaty obligations," he said.

Mayor Eric Adams and multiple NYPD officials briefed reporters Saturday on the security posture ahead of former President Trump’s rally tomorrow at Madison Square Garden.

Adams said New Yorkers should expect a "large police presence" around MSG, including "protections you will see, and many you won’t see."

NYPD Deputy Commissioner Rebecca Weiner and NYPD Chief of Patrol John Chell told reporters officials are expecting protests and that there will be designated areas for people to lawfully exercise their First Amendment rights.

The police will begin their security preparations after Friday night's Rangers game.

“You will see a heavy uniformed presence around the Garden, you’ll see heavy-weapons teams, counter-terror, aviation… blocker vehicles and many more,” Chell said.

Speaking to potential protesters, Adams said no one should "come to our city to try to cause problems."

After receiving a three-minute ovation following an introduction from Michelle Obama at Kalamazoo, Michigan, Vice President Kamala Harris touted her history and plans for the future if elected.

"We are here as community as coalition builders, because we love our country," she said.

At one point Harris' speech was interrupted by a heckler who was protesting the Israel-Gaza war, but that person was drowned out by the crowd. Harris addressed the heckler's concerns.

"On the topic of Gaza, we need to end that war. We need to end that war and bring the hostages home, but now I'm talking about 2024," Harris said.

The vice president spoke about many of her policies including one that would allow Medicare to pay for home health care for senior citizens.

"A lot of people right now living in what we call the sandwich generation, [those] who are taking care of your kids while you're taking care of your parents. That's a lot," she said.

Harris picked up the conversation on reproductive rights and noted that one in three women live in a state with restrictive abortion bans.

"Donald Trump still refuses to even acknowledge the pain and suffering he has caused. He insists that ... everybody wanted Roe V. Wade to be overturned. Come on. Everyone wanted this?" Harris said.

"Women are being denied care during miscarriages, some only being treated once they develop sepsis. They didn't want this. Couples just trying to grow their family who have been cut off from IVF treatments. They didn't want this."

Harris addressed Gen Z voters talking about their fears and struggles living in a world with gun violence, reduced reproductive rights and dangers of climate change.

"All these issues are not theoretical. They're not political. They're your lived experience. And I want to tell you I see you, and I see your power," she said.

Former first lady Michelle Obama took the stage at Kalamazoo, Michigan, to a roaring ovation before introducing the vice president.

Obama, in her first campaign appearance since the DNC, spoke about Harris' mature temperament and history of working for all Americans.

"Michigan, do not buy into the lie that we do not understand who Kamala is or what she stands for," she said.

"Take it from me, I know good people," Obama said.

She questioned "why on Earth this race is even close," but contended that Kamala has shown she is ready for the job.

"The real question is, are we ready for this moment?" Obama said.

The former first lady said she was angry at the indifference shown to Donald Trump over his history of division, bias and lack of care for democracy.

"Some folks think he's funny. That's how he got elected the first time. Folks gave him a pass and rolled the dice, betting that he couldn't possibly be that bad," she said.

"Nothing this man says or does is funny in any way," Obama later added.

The former first lady addressed the men in the crowd when talking about the stakes of women's health and reproductive rights if Trump wins.

She talked about the loss that many women have seen in the last three years through the loss of reproductive care following the Dobbs decision and the dangers if Trump pushes for more restrictions.

"Your girlfriend could be the one in legal jeopardy if she needs a pill from out-of-state or overseas, or if she has to travel across state lines because the clinic closed up. Your wife or mother could be the ones at higher risk of dying from undiagnosed cervical cancer because they have no access to regular gynecological care. Your daughter could be the one to terrified to call the doctor if she's bleeding during an unexpected pregnancy," she said.

"So fellas, before you cast your vote, ask yourselves, what side of history do you want to be on?" Obama later added.
