US President Joe Biden has spoken at a rally in North Carolina - his first public event since he struggled in the first televised debate of the 2024 presidential campaign. He directly addressed concerns about his age, admitting he doesn't debate like he used to, but "when you get knocked down, you get back up". His Republican opponent, Donald Trump, also held a rally. He boasted to voters in Virginia about his past presidential record and claimed victory in Thursday's debate.
