RFK Jr. is expected to drop his Democratic primary bid and launch an independent or third-party run

Anti-vaccine activist Robert F. Kennedy Jr. is expected to announce Monday that he will drop his Democratic bid for president and run as an independent or third-party candidate, adding a new wrinkle to a 2024 race currently heading toward a rematch between President Joe Biden and former President Donald Trump.

Kennedy’s campaign has teased the announcement in the days leading up to a Monday afternoon speech in Philadelphia. In a recent video, Kennedy said there is corruption “in the leadership of both political parties” and said he wants to “rewrite the assumptions and change the habits of American politics.”

The video came shortly after Mediaite reported he planned to launch an independent bid.
