President Donald Trump and his Democratic rival Joe Biden have one last chance to debate each other ahead of Election Day on November 3.
The two candidates will go head-to-head in a televised debate held in Nashville, Tennessee, tonight.
It's the third debate between the presidential candidates scheduled - but only the second debate to go ahead after the last one was cancelled.
Their first debate last month was punctuated by frequent interruptions, mostly from Mr Trump, leaving the two men talking over each other and Mr Biden eventually telling the president to “shut up”.
The second one was scrapped after Mr Trump was diagnosed with coronavirus and refused to participate in a virtual debate.
Tonight's debate will see some format changes following their last clash.
Each candidate’s microphone will be turned off while his opponent gives a two-minute answer to an initial question on each debate topic.
The debate will be moderated by NBC News White House correspondent Kristen Welker.
She will be the first black woman to serve as the moderator of a presidential debate since Carole Simpson in 1992.
The debate will be divided into six 15-minute segments, each on a topic selected by Ms Welker: Fighting Covid-19, American families, race in America, climate change, national security and leadership.
The debate, which takes place at Belmont University, will start at 9pm EDT - which is 2am in the UK.
It is scheduled to last for 90 minutes with no commercial breaks.
The BBC's 24 hour news channel will have coverage of the debate, as will Sky News.
If you're not willing to stay up to catch the action live, you can re-watch them on the BBC iPlayer or on YouTube.
In the US, all major networks will be broadcasting the debate including ABC, CBS, NBC and Fox News.
