RFK Jr. announces 2024 presidential bid, vows to fight corporate power and challenge Biden.

Robert F. Kennedy Jr., a prominent anti-vaccine activist and nephew of former President John F. Kennedy, announced his candidacy for the 2024 presidential election as a Democrat. He is the second Democrat to run for president in 2024 after Marianne Williamson. President Joe Biden is expected to run for a second term, but has not yet made a formal announcement. Kennedy's history of propagating anti-vaccine theories has made him well known, and he railed against drugs and vaccines in his campaign launch speech. While polling shows most Democratic voters want someone other than Biden to be the party's candidate in 2024, the party has signaled it will stand behind the incumbent president if he seeks reelection.
