Harris, Trump ramp up efforts to win swing state voters

AMNA NAWAZ: And turning now to the presidential race, with just over 40 days until Election Day, both Vice President Kamala Harris and former President Donald Trump are ramping up their campaigning in swing states during the final stretch of the race.

A week after a second attempt on his life, former President Donald Trump spent the afternoon in Western Pennsylvania.

DONALD TRUMP, Former President of the United States (R) and Current U.S. Presidential Candidate: Nobody's done for farmers what I have done.

AMNA NAWAZ: Speaking to voters about the potential threat from China to U.S. agriculture.

DONALD TRUMP: I'm going to call up President Xi.

I'm going to say, you have to honor the deal you made.

We made a deal you would buy $50 billion worth of American farm product, and I guarantee you he will buy it, 100 percent.

He will buy it.

AMNA NAWAZ: As Trump and Vice President Harris barnstorm battlegrounds just six weeks before Election Day, new polling from The New York Times and Siena College shows the former president taking the lead in three of those crucial states, Arizona, Georgia and North Carolina, with Trump's five-point lead in Arizona outside the margin of error.

While the polls may show a Trump advantage in the Sun Belt, Harris is outpacing her Republican rival when it comes to money in the bank.

The vice president received a $27 million cash injection from a Wall Street fund-raising event on Sunday, adding to the $361 million the campaign raised last month.

That same day, she also racked up 700 endorsements in a signed letter from both Republican and Democratic national security leaders, who called the choice between Harris and Trump a choice between -- quote -- "democracy and authoritarianism."

On official vice presidential business today, Harris will pick up campaigning in key swing states throughout the week with a focus on the economy.

KAMALA HARRIS, Vice President of the United States (D) and U.S. Presidential Candidate: I have named it an opportunity economy, which really, in short form, it's about what we can do more to invest in the aspirations, the ambitions and the dreams of the American people, while addressing the challenges that they face.

AMNA NAWAZ: The vice president also accepted an invitation from CNN for a second debate with Donald Trump, who swiftly declined the invitation at a weekend rally.

DONALD TRUMP: It's just too late.

Voting has already started.

AMNA NAWAZ: And in an interview on a conservative Sunday show, Trump was candid about his plans not to run again in 2028.

QUESTION: If you're not successful this time, do you see yourself running again in four years?

DONALD TRUMP: No, I don't.

No, I don't.

I think that will be -- that will be it.

I don't see that at all.

AMNA NAWAZ: His running mate, Senator J.D.

Vance, meanwhile, campaigned in North Carolina today.

SEN. J.D.

VANCE (R-OH), Vice Presidential Candidate: Thanks to Kamala Harris' policies, you have got a lot of American families and a lot of American cities that can't afford to provide basic necessities to their citizens.

AMNA NAWAZ: But all eyes are on a different Republican candidate in the Tar Heel State, gubernatorial nominee Mark Robinson.

On Sunday, several of Robinson's top campaign staffers quit after a CNN report uncovered numerous inflammatory and derogatory comments that the lieutenant governor allegedly made on a porn Web site.

The Harris campaign quickly turned out campaign ads tying Robinson directly to Donald Trump.

DONALD TRUMP: I have gotten to know him and he's outstanding.

NARRATOR: Donald Trump and Mark Robinson, they're both wrong for North Carolina.

AMNA NAWAZ: With early voting already under way in some states, the race remains a tight one, leaving a grueling sprint ahead for the candidates in the weeks until November.
