Embattled Joe Biden to give high-stakes press conference

US President Joe Biden faces a critical moment in his presidency as he prepares for his first solo press conference since 2023. The 81-year-old leader is under intense scrutiny from his own party, with calls to step aside over concerns about his age and health. A poor performance could have significant implications for his reelection bid, with pressure mounting from within the Democratic party. Biden's ability to handle unscripted moments will be put to the test at the NATO summit, where world leaders are seeking reassurance about his leadership abilities.
