Watch as Donald Trump arrives in Philadelphia to face off against Kamala Harris in a presidential debate hosted by ABC on Tuesday 9 September.
Tuesday night marks their only scheduled debate of the US presidential campaign, and it will be a key moment in a close-fought contest.
Ms Harris and Mr Trump go head-to-head in a clash that begins at 9pm ET, just eight weeks before the 5 November election and days before early voting will start in some states.
Former President Trump said he would contrast the left-wing policies Ms Harris proposed in her failed 2020 presidential bid with the more centrist positions she has staked out now.
“You don’t know what to expect. She’s changed all of her policies over the years,” he told NBC News in a phone interview ahead of the debate.
Ms Harris, meanwhile, indicated she will draw attention to Mr Trump’s habit of lying.
“Donald Trump has a real problem with the truth,” she wrote in a social media post Tuesday morning.
Her campaign also released an ad featuring former president Barack Obama ridiculing Mr Trump’s false claims about crowd sizes at his events.
