WASHINGTON — Antivaccine activist Robert F. Kennedy Jr. filed paperwork on Wednesday to run for president as a Democrat in a long-shot bid against President Biden.
Mr. Kennedy, son of former Attorney General Robert F. Kennedy and nephew of former President John F. Kennedy, declared his candidacy by filing a statement with the Federal Election Commission. He joins self-help author and activist Marianne Williamson in a 2024 Democratic field that is unlikely to include any major challengers to Mr. Biden.
