Robert F. Kennedy Jr. announces 2024 presidential bid, challenging Biden and promoting anti-corporate platform.

Robert F. Kennedy Jr., an anti-vaccine activist and environmental lawyer, has launched his bid for the 2024 Democratic presidential nomination in Boston. Kennedy used his campaign launch speech to criticize school and business closures during the pandemic and to insist that government and media "lie to us." He faces opposition from some members of his own family due to his views on vaccines. Kennedy is the latest in a long line of family members to seek to enter politics. The 2024 Democratic presidential primary is only beginning to take shape, with self-help guru Marianne Williamson also in the race.
