Vice President Kamala Harris has accepted a CNN invitation to a presidential debate on 23 October, just days before the November election.
It is unlikely that her rival Donald Trump will accept the invitation, although last week he suggested he would be open to the possibility.
The two faced off in a previous debate in Philadelphia on 10 September.
The CNN debate in October would follow the same format as a June debate between Trump and President Joe Biden, the then-Democratic candidate.
In a statement on Saturday, Harris-Walz campaign chair Jen O’Malley Dillon said that Americans “deserve another opportunity” to see Harris and Trump debate before the November election.
“It would be unprecedented in modern history for there to just be one general election debate,” she added. “Debates offer a unique chance for voters to see the candidates side by side and take stock of their competing visions for America.”
On X, formerly Twitter, Harris said that she “gladly” accepts the debate and hopes Trump will also take part.
After the 10 September debate, Trump had said there would be no further debates.
When contacted by the BBC, the Trump campaign referred to a 12 September social media post in which the former president claimed victory in the last debate and said there “will be not be a third debate”.
Last week, however, Trump suggested he might be open to a possible rematch.
“Maybe if I got in the right mood,” he told reporters in California.
Harris holds a slight lead over Trump in national polling averages.
Snap polls released immediately after the 10 September debate found that most viewers thought Harris had been the better performer.
Since then, a majority of national polls suggest that Harris has made small gains with voters.
The two candidates exchanged swipes and barbs at the previous debate, with Trump calling Harris a “radical left liberal” and a Marxist who was destroying America.
Harris, for her part, goaded Trump, belittled the size of his rally crowds and quoted his Republican detractors.
CBS, the BBC’s news partner in the US, has also invited both presidential candidates to participate in an October debate in Arizona.
