Santita Jackson confirmed that her father died at home in Chicago, surrounded by family.
As a young organizer in Chicago, Jackson was called to meet with King at the Lorraine Motel in Memphis shortly before King was killed and he publicly positioned himself thereafter as King's successor.
Jackson had his share of critics, both within and outside of the Black community. Some considered him a grandstander, too eager to seek out the spotlight. Looking back on his life and legacy, Jackson told The Associated Press in 2011 that he felt blessed to be able to continue the service of other leaders before him and to lay a foundation for those to come.
In his final months, as he received 24-hour care, he lost his ability to speak, communicating with family and visitors by holding their hands and squeezing.
