President Donald Trump and his Democratic challenger Joe Biden clashed in Cleveland, Ohio, on the last Tuesday of September in the first of three scheduled debates ahead of November's election.
The two candidates went toe-to-toe on the coronavirus pandemic, race relations, the president's recently revealed tax records and the economy, in what has been described as the most chaotic and bad-tempered debate in living memory.
Mr Trump repeatedly interrupted Mr Biden, making it difficult for the Democrat to get a word in during the fiery exchanges, leading some commentators to suggest there was no real winner in the contest.
When Mr Biden did get a chance, he made a point of addressing the camera, trying to speak directly to voters, while the president stared at him balefully.
Former vice president Biden was at times was able to squeeze in the key themes of his candidacy - that Mr Trump was unfit for a second term over his handling of the pandemic.
In a dig at the president's flagging support with the critical suburban voting bloc. He said: "He wouldn't know a suburb unless he took a wrong turn."
Trailing badly in all major polls, the president will be hoping his attacks get more cut through at the next debate, where the two men are likely to cover the same topics, as they attempt to win over voters with just over a month to go until election day.
That contest will take place in Florida's Adrienne Arsht Center for the Performing Arts in Miami on 15 October. Proceedings kick off at at 9pm ET (2am in the UK).
