The family of Emmett Till says a letter from Lil Wayne fell short of an apology for his crude reference to the civil rights martyr, and they want a meeting with the rapper and representatives from PepsiCo to discuss their commercial partnership.
A publicist for the Rev. Al Sharpton says he is attempting to arrange a meeting between the parties to work out differences over Wayne's vulgar reference to the slain teen in a song lyric.
Till was brutally murdered in Mississippi in 1955 after allegedly whistling at a white woman. Wayne has a contract to promote PepsiCo product Mountain Dew.
Sharpton's efforts come after Lil Wayne sent an empathetic letter to the family that stopped short of an apology.
Wayne's publicist said he would have no immediate comment.
