Breaking: US President Joe Biden drops out of 2024 presidential race

US President Joe Biden announced Sunday that he will end his presidential re-election campaign, bringing an abrupt and humbling conclusion to his half-century-long political career and scrambling the race for the White House just four months before Election Day.

Biden, 81, could not reverse growing sentiment within his party that he was too frail to serve and destined to lose to Donald Trump in November.

Biden said “it is in the best interest of my party and the country”.

In a letter posted to his social media account, he said it had been the greatest honour of his life to serve as president.
