Harris is expected to announce her running mate in the coming days.
Vice President Kamala Harris has secured enough Democratic Party delegate votes to become the party's nominee when voting ends on Monday, according to the Democratic National Committee. And Harris is just days away from naming her running mate.
Former President Donald Trump and his vice presidential pick, Sen. JD Vance, have spoken to voters across the country this past week as they sharpen their attacks on Harris.
Harris told reporters she still hasn’t decided who her running mate will be as she boarded a plane Tuesday for a trip to Atlanta.
“Madam vice president, have you chosen your VP yet? Have you chosen yet?” ABC News' Fritz Farrow asked.
“Not yet,” Harris said with a smile as she stopped midway up the steps of Air Force Two.

President Joe Biden told reporters Monday night after returning from a trip to Texas that he's "talking" with Harris about her choices for vice president.
Biden was also asked about hitting the trail for Harris, and said he "did" with his trip.

As Vance continues to face criticism for his 2021 comments about "childless cat ladies," more of his previous comments about individuals without kids have resurfaced.
In a podcast from November 2020, Vance said those without kids -- especially in America's leadership class -- were "more sociopathic" than those with kids and made the country "less mentally stable."
Vance's comments occurred on the podcast after he discussed the impact having children had on him.
Vance also added that the "most deranged" and "most psychotic" people on Twitter, now known as X, are people who don't have kids.
"There's just these basic cadences of life that I think are really powerful and really, really valuable when you have kids in your life, and the fact that so many people, especially in America's leadership class, just don't have that in their lives, you know, I worry that it makes people more sociopathic, and ultimately, our whole country a little bit less less mentally stable," Vance said in the podcast.
"And of course, you talk about going on Twitter. Final point I'll make is you go on Twitter, and almost always the people who are most deranged and most psychotic, are people who don't have kids at home."
CNN was the first to report on the podcast.

Trump's campaign is targeting Harris in its biggest television ad buy since at least January, reserving eight-figure dollar worth of airtime in six key battleground states, according to ad tracking firm AdImpact.
The 30-second ad zeroes in on the rhetoric that Harris "failed" in her role handling immigration issues in President Biden's administration, calling her "weak" and "dangerously liberal."
"This is America's border czar, and she's failed us. Under Harris, over ten million illegally here, a quarter of a million Americans dead from fentanyl, brutal migrant crimes, and ISIS now here," a narrator in the ad says, followed by an interview clip of Harris appearing to admit she hasn't visited the border.
Harris was assigned to address the root causes of migration in Central and South America. She made one visit to the southern border operations in June 2021.
The Harris campaign hit back that Trump was responsible for "killing the toughest border deal in decades" and accused him of misrepresenting her record.
"As a former district attorney, attorney general, and now vice president, Kamala Harris has spent her career taking on and prosecuting violent criminals and making our communities safer. She'll do the same as president," said Harris campaign spokesperson Ammar Moussa.
