Robert F Kennedy Jr to challenge Biden for White House

Robert F Kennedy Jr has filed election paperwork to run for US president in 2024 as a Democrat.

The 69-year-old is the son of assassinated Senator Robert F Kennedy and nephew of President John F Kennedy.

The environmental lawyer's campaign treasurer, John E Sullivan, confirmed the filing to CNN on Wednesday.

Mr Kennedy is an outspoken anti-vaccine campaigner. Instagram removed his account in 2021 for "repeatedly sharing debunked claims", the company said.

US President Joe Biden has indicated he will run for re-election, though he has not yet formally declared his candidacy.

In March, Mr Kennedy shared on Twitter that he was considering a run for president.

At the time, he said: "If I run, my top priority will be to end the corrupt merger between state and corporate power that has ruined our economy, shattered the middle class, polluted our landscapes and waters, poisoned our children, and robbed us of our values and freedoms."
