Harris-Trump ABC News presidential debate: How to watch and what you should know

President Donald Trump and Vice President Kamala Harris will face off next week in their first debate of the 2024 election, moderated by ABC News.

With only a few weeks left until Election Day, the debate offers both candidates a crucial opportunity to win over undecided voters in what is expected to be a close election campaign.

The debate is an opportunity for Harris – who became the Democratic nominee after President Joe Biden dropped out of the race following his lackluster debate performance in June – and Trump to explain their policies on key issues. It is the first time the two have met in person.

In addition, the debate is a first opportunity for Trump to attack Harris while also laying out some of his own positions.

Here you can find out everything you need to know about the debate and how you can tune in.
