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

With only weeks until Election Day, the debate is a crucial opportunity for both candidates to work to sway undecided voters in what's expected to be a close contest.

The debate is a chance for Harris -- who became the Democratic candidate after President Joe Biden left the race following his lackluster June debate performance -- and Trump to explain their policies on key issues. It’s the first time the pair will meet in person.

Likewise, the debate is Trump's first opportunity to attack Harris while laying out some of his own positions.
