Sean King's attendance at Rihanna's Diamond Ball, where he was honored for his work with the Clara Lionel Foundation, served as a catalyst for his feud with DeRay McKesson. Rapper Cardi B publicly defended King on Instagram, urging her followers to support his "Vote for Senate" initiative. King argues that McKesson's attacks were timed to overshadow the charity event and dismiss the intelligence of the high-profile women supporting him.
