Appearing at Tucker Carlson’s fireside chat style interview for his final stop of the Western swing in Arizona, former President Donald Trump suggested that there is an "enemy within" and if there is a “smart president” in office, the country will be fine.

“We do have an enemy from within. We have some very bad people, and those people are also very dangerous. They would like to take down our country. They'd like to have our country be a nice communist country or a fascist in any way they can. And we have to be careful of that,” Trump said.

“They're the threat to democracy. You know, the amazing thing -- the amazing thing is where they say, ‘He wants to become elected, and he wants to put people in jail.’ How terrible. That's what they've been trying to do to me for four years,” Trump said, reminding his followers of the legal battles he’s gone through.

Trump repeatedly threw personal attacks on Rep. Adam Schiff, attacking his appearance and suggesting he’s an example of a Democrat who “hates the country” because he led the efforts of Russian intelligence in the 2016 election.

“Schiff, he's a sleazebag, and he's probably going to be a senator, if you can believe it,” Trump said, pointing to an example of Democrats who he alleges “hate the country.”

“He's unattractive both inside and out," Trump said. "But this is a really bad guy. This is a dishonest guy, not a dumb guy at all."

Vice President Kamala Harris vowed that "nothing in the world" will prevent her from fighting for Americans while speaking in Reno, Nevada, on Tuesday.

She referenced her time as a prosecutor in the neighboring state of California, saying, "A lot of folks here know I'm not afraid of tough fights."

“And it is my pledge to you that if you give me the chance to fight on your behalf as president, there is nothing in the world that will stand in my way of fighting for you,” Harris added. “For the people.”

During her first general election rally in the northern part of Nevada, she also criticized former President Donald Trump's comments on protecting women.

“He said, on the issue of freedom of choice, reproductive freedom, he said that he will do what he wants because, quote, he -- this is his perspective -- he will do it ‘whether the women like it or not,’ ‘whether the women like it or not,’” Harris said. "Can you imagine?"

“He does not believe women should have authority or agency over their own bodies. This is the same person who said that women should be punished for their choices," she said, echoing remarks that she'd made at campaign stops throughout the day. "This is someone who simply does not respect the freedom of women, or the intelligence of women to make decisions about their own lives."

She closed out the rally with a phrase she's employed over the past several days, telling those in the crowd that "in less than 90 days, either he or I will be sitting in the Oval Office," explaining that while Trump will walk into that room with an enemies list, she is prepared to walk in with a to-do list.

Although Harris' remarks were interrupted a few times by protestors, she addressed them saying, "We're here because we're fighting for a democracy."

She said it was "okay" and "all right" for them to protest at the event, because "we're fighting for the right to be heard and not be jailed for speaking their mind."

"We know what's at stake," Harris assured.

At his second campaign stop of the day, former President Donald Trump was set to make his final pitch to voters from the populous Las Vegas metropolitan area just five days ahead of Election Day.

But Trump seemed noticeably low energy Thursday evening as his speech gradually strayed from his key campaign messaging to ramble about topics like his social media company.

Despite this, Trump repeatedly bashed Vice President Kamala Harris for appearing tired, while touting that he has been campaigning for 62 days in a row.

“Five days -- I can't wait. You know what? I've worked for 62 days in a row. I haven't taken a day off,” Trump said at the rally. “I looked at her today. She was trying to justify the fact that they called us all garbage. And I watch her do news coverage. She's exhausted. She's finished,” he said of Harris.

With just days until the election, Georgia's top election official warned Thursday that a fake video circulating online claiming to show voter fraud in the state is "likely foreign interference attempting to show discord and chaos on the eve of the election."

The video circulating on social media, according to Georgia Secretary of State Brad Raffensperger, purports to show a Haitian immigrant claiming to have voted multiple times with multiple state IDs.

"This is false," Raffensperger said of the video, calling it "targeted disinformation."

Raffensperger's statement said law enforcement is investigating, and added it is "likely" a product of Russian troll farms. Raffensperger called on social media companies to take the video down -- and specifically called out Elon Musk by name.

"As Americans, we can’t let our enemies use lies to divide us and undermine our faith in our institutions -- or each other," he said.

Harris and her allies in battleground Michigan are launching a new turnout campaign to assertively shore up support among Arab Americans, sending out mailers using Trump's own words about reimplementing a Muslim ban.

"Just last month, Donald Trump said he would ban Muslims from traveling here, and also ban refugees from Gaza," one of the mailers obtained by ABC News reads. Further down, the mailer says the former president "is no friend to Arab Americans," with one of their examples being his comment that he would let Israel "finish the job" in Gaza.

Another is a full-page black-and-white photo of Trump with "FINISH THE JOB" written above him. "That's what Trump said he would let Israel do in Gaza." The mailers, which come on the heels of a six-figure digital ad push, also points to the Arab American group Emgage Action's endorsement of Harris. (A number of other Arab leaders have backed Harris.)

Michigan, a state that was narrowly won in 2016 and 2020, is a target of both Harris and Trump's campaigns and has the largest Arab-American population among the states that will help decide the election. And Trump is making a play for them, too. Over the weekend, in Novi, Michigan, Trump invited Muslim leaders to the stage who are backing him, including Hamtramck, Michigan, Mayor Amer Ghalib.

Pro-Palestinian protestors who take issue with the U.S. response have demonstrated at Harris' rallies, including on Tuesday night as she delivered her "closing argument" speech outside the White House and Wednesday at a rally in Harrisburg, Pennsylvania.

"Look, I'll repeat: We are fighting for our democracy. We love our democracy. It can be complicated at times, but it is the best system in the world," Harris said after several interruptions from demonstrators.
