Harris was joined in Detroit by pop stars Lizzo and Usher at campaign rallies in Atlanta, where the Democratic nominee referred to her Republican rival as exhausted and troubled.
Trump, who is running for a second term in the White House, responded to these accusations with a marathon speech in Pennsylvania, while billionaire Elon Musk campaigned on his behalf elsewhere in the state.
Both candidates are fighting on all fronts for voter support in a race that opinion polls indicate is virtually tied less than three weeks before Election Day.
Harris told voters in Detroit that her opponent’s platform is “self-consuming” as he reiterates his pledges to invest in the working and middle classes.
“We support the idea that the true measure of a leader’s strength is not who you defeat, but who you lift up,” Harris said.
Later in Atlanta, she accused the 78-year-old Trump of “dodging debates and canceling interviews due to exhaustion.”
“When he answers a question or speaks at a rally, have you noticed that he tends to go off script and rave, and generally, for the rest of his life, cannot finish a thought?” she said.
“He called it weaving. But here we’ll call it bullshit.”
Trump began his more than 90-minute rally with a lengthy monologue about golfer Arnold Palmer, after whom the Latrobe Regional Airport, where the Republican appeared, is named.
He then launched into a meandering routine that included attacking immigrants, denigrating Harris personally, and repeating false claims about the 2020 election.
But it was a display of endurance on stage, which also included a number of guests and performances of his campaign video ads.
Shortly after recalling his expensive education at a private Ivy League university in Pennsylvania, Trump vied to appeal to working-class voters by bringing a parade of steelworkers wearing hard hats on stage.
He also stressed the importance of the eastern state’s Electoral College delegates in the general election: “If we win Pennsylvania, we’ll win the whole thing.”
Earlier in the day, pop star Lizzo noted, “Whether you’re a Democrat, Republican, or neither, you deserve a president who listens when you speak.”
“You deserve a president who respects you when you protest. “You deserve a president who understands that his job is to be a public servant,” she said, before emphasizing that Harris offers just that.
Lizzo, who wore a white suit while addressing crowds in the Motor City, also drew cheers when she urged listeners that America was more than ready for its first female president, and dropped a reference to her hit song: “It’s About Time.” !
Asher, one of Atlanta’s major stars, told voters there: “I’m counting on you” to get “the Harris campaign over the finish line” in Georgia.
Both candidates are spending their final campaign days in pivotal states where early voting is already underway.
Musk, who endorsed Trump in July, is one of the Biden administration’s harshest critics and has emerged as a loud voice in US politics since its acquisition of Twitter, now known as X.
The Tesla and SpaceX CEO has played an increasingly prominent role in Trump’s campaign and donated about $75 million to his political organization America PAC.
Speaking in Harrisburg, Pennsylvania, he announced he would begin handing out random cash prizes, worth $1 million a day until the November 5 vote, to registered voters in the state who signed his organization’s petition.
