US Vice President Kamala Harris will call on Americans to “turn the page” on rival Donald Trump as she delivers her closing argument in the presidential race at a location that recalls the January 6 riots.

Harris will make her final pitch to voters in Washington at the same spot where then-US president Trump gave a speech in 2021 to supporters who then stormed the US Capitol.

The Democrat will speak at Ellipse, a park near the White House where Trump told protesters to “fight like hell” and march down Pennsylvania Avenue after he lost the 2020 election.

During the speech, Harris will call on Americans to “turn the page” on Trump, while stressing her plans to lower costs and make the economy work for middle-class Americans, a senior Harris campaign official said.

The rally venue, with the White House in the background, was both symbolic of the good a president could do to bring the country together and get things done and a time when a president, focused only on himself, incited a violent mob to try to put himself above the country, the official said.

Trump, meanwhile, has falsely said Democrats had staged a “coup” to force President Joe Biden to drop his re-election bid.

At an event at his Florida estate a week before the November 5 election, Trump said Harris would be too dangerous to serve as president, pointing to foreign wars and high levels of immigration that have occurred while she has been Vice President.

His accusation that Democrats had unfairly forced Biden out of the race recalled Trump’s false claims that he had lost the 2020 election due to fraud.

“They stole the presidency of the United States. You can call it a coup, you can call it whatever. But they stole it,” he told supporters.

“The way they took that away from him was not right.”

Biden, 81, abandoned his re-election bid in July after weeks of pressure from fellow Democrats who worried he was too old for a rematch with Trump, 78.

Throughout her campaign, Harris has tried to paint Trump as a threat to democracy who will infringe on the rights of Americans, including on the reproductive rights of women.

For his part, Trump has sought to tie Harris to Biden’s handling of immigration and the economy.

In a Reuters/Ipsos poll published last week, Harris held a marginal 46 per cent to 43 per cent lead over Trump.

Trump will on Tuesday (US time) launch the final week of his campaign in remarks at his Mar-a-Lago home that an adviser characterised as a prebuttal to her speech.

Later he will visit a heavily Hispanic city in Pennsylvania, two days after his rally at Madison Square Garden in New York was criticised because of an ally’s vulgar and racist remarks about Latinos and Puerto Ricans.

In a speech at Sunday’s rally, Trump spoke repeatedly about his plans, if re-elected, to halt illegal immigration and deport migrants he described as “vicious and bloodthirsty criminals”.

Comedian Tony Hinchcliffe, who opened for Trump along with tech billionaire Elon Musk and former New York City mayor Rudy Giuliani, called the Caribbean US territory of Puerto Rico a “floating island of garbage” and disparaged black Americans, Jewish people and Latinos.

Harris has spent the past week appearing with high-profile celebrities to try to draw voters to the polls.

She held a rally with Bruce Springsteen in Atlanta on Thursday and with Beyonce in Houston on Friday.
