Robert Kennedy Jnr to challenge Joe Biden in US presidential bid
- He faces little chance of success, but his campaign could help advance his claims that childhood Covid-19 immunisations pose health risks
- A member of the Kennedy political dynasty, he has been banned from YouTube and Instagram for spreading misinformation about vaccines and the pandemic

Anti-vaccine activist Robert F. Kennedy Jnr, a member of a storied US political dynasty, is due to announce on Wednesday a long shot bid to challenge incumbent President Joe Biden for the 2024 Democratic presidential nomination.
Kennedy, 69, faces little chance of success, but his campaign could help him to advance claims that childhood immunisations pose health risks – a theory that has been repeatedly discredited by multiple scientific reviews.
Kennedy has been banned from YouTube and Instagram for spreading misinformation about vaccines and the Covid-19 pandemic.
He is the nephew of former President John F. Kennedy, who was assassinated in 1963, and the son of former US Senator Robert F. Kennedy, who was assassinated in 1968 during his own presidential bid.
Kennedy is likely to highlight these links when he makes his announcement in Boston, the city where his uncles – also including the late US Senator Edward Kennedy – launched their political careers.
