Republican Donald Trump has appealed to religious voters in the southern swing state of Georgia as his campaign distanced itself from racist remarks by allies that could alienate key voter groups.
Millions of Americans have already cast their vote before the US election, which polls show is essentially a dead heat between Trump and his Democratic rival Kamala Harris.
In Georgia, where in-person early voting ahead of Election Day is expected to total up to 70 per cent of ballots, Trump courted religious voters during a National Faith Advisory Board event.
"I think this is a country that needs religion," Trump said. "They're trying to stymie you, this new administration, this new radical left group of people."
But he faces pressure over his rally in New York on Sunday, where a comedian called Puerto Rico a "floating island of garbage," prompting a backlash from Latino celebrities and criticism from both Republican and Democratic politicians. The Trump campaign has said the joke did not reflect their views.
Harris said Trump "fans the fuel of hate and division, and that's why people are exhausted with him." Later, Trump rejected Harris' contention that he is a fascist telling thousands at a rally in Atlanta: "I'm not a Nazi. I'm the opposite of a Nazi."
Earlier, Trump had been attacking Harris by falsely claiming she was letting “some of the worst criminals in the world into our country”.
“Kamala has imported criminal migrants from prisons and jails, from insane asylums and mental institutions, from all around the world - from Venezuela to the Congo,” he said.
Georgia is one of seven competitive swing states expected to play a decisive role in an election that wraps up in just eight days. National polls including the Reuters/Ipsos poll and surveys in swing states show the two candidates in a close match.
At stake in this election is stewardship of the world’s most powerful country. Harris and Trump diverge on support for Ukraine and NATO, tariffs that could trigger trade wars, abortion rights, taxes and basic democratic principles.
Some 46 million Americans have voted already, according to the Election Lab at the University of Florida, including some 2.8 million people in Georgia and 1.9 million people in Michigan, where Harris arrived on Monday.
That trails the roughly 60 million people that had voted early by about this point in 2020, at the height of the COVID-19 pandemic.
Harris visited Corning Inc's Hemlock Semiconductor facility to talk to workers and tour the assembly line and talk about the importance of investing in manufacturing jobs.
The company recently received a preliminary investment of up to $US325 million via the Chips and Science Act, which a Harris campaign official noted Trump had criticised and Harris helped pass.
"When we can find a way to have meaningful partnerships with the private sector, with industries, but to do the kind of work that is happening here, everybody wins," she said.
Trump has argued his stewardship of the economy was stronger than that of President Joe Biden and Harris, despite major job losses at the end of his term at the onset of the COVID-19 pandemic.
Harris has issued policy proposals to bring down prices and help alleviate America's housing crunch, while also contrasting her leadership approach with Trump, who she said would be focused on getting back at his enemies.
On Monday evening, Harris appeared at a rally in Ann Arbor, Michigan with her running mate, Minnesota Governor Tim Walz, that featured a performance by singer-songwriter Maggie Rogers.
The Democrat made a rare reference to climate change, an issue that has been almost totally absent from the 2024 campaign so far.
Addressing young voters, she said: “You are impatient for change because, you have only known the climate crisis and you are leading the charge to protect our planet and our future.”
