Tonight marks the first joint appearance of Biden and Trump since their encounters four years ago.
This debate is historic, being the earliest in modern US history, occurring before either candidate is the official nominee of their party.
Unlike previous debates, there will be no live audience, as requested by the Biden campaign, and microphones will be muted while the other candidate speaks to avoid the chaos seen in 2020.
This event will not be a friendly reunion, as it is the first time a current US President will debate his predecessor.
This will be the second time Donald Trump and Joe Biden share the debate stage in four years. The 2020 debate was notably contentious with frequent interruptions.
The outcome of tonight’s debate could significantly impact the upcoming election, raising the stakes. The candidate who effectively delivers memorable lines and skillfully defends their weaknesses could emerge as the winner.
