US President Joe Biden tripped on a sandbag during a graduation ceremony. Biden, 30, is currently the oldest person to occupy the White House.

The US president is running for re-election in the 2024 election, while Donald Trump, also a candidate, will celebrate his 77th birthday. The latter regularly criticizes his successor regarding his age and state of health. "He's fine. There was a sand bag on the stage as he shook hands," White House said on Twitter.
