Three former U.S. presidents, Grammy-winning artists, clergy and elected officials are expected to attend a Chicago celebration of life Friday for the late Rev. Jesse Jackson Sr. The event honoring the protege of the Rev. Martin Luther King Jr. and two-time presidential candidate follows memorial services that drew large crowds in Chicago and South Carolina, where the civil rights leader was born. The Chicago celebration is expected to be the largest. Former Democratic U.S. presidents Barack Obama, Joe Biden and Bill Clinton are listed as speakers. That's according to the Rainbow PUSH Coalition, the organization that Jackson founded.
