Kamala Harris and Donald Trump will meet for the first time face-to-face Tuesday night for perhaps their only debate, a high-pressure opportunity to showcase their starkly different visions for the country after a tumultuous campaign summer.

Kamala Harris and Donald Trump will face off in a presidential debate this week at the National Constitution Center in Philadelphia. How to watch.

Moderated by World News Tonight anchor David Muir and ABC News Live anchor Linsey Davis, the debate saw both candidates outline their visions for the country. The event featured no live audience and strictly enforced rules on time limits, with microphones muted when either candidate was not speaking.
