The Rev. Al Sharpton is slated to discuss "conservative right-wing attempts" to discredit Nate Parker and his upcoming film, The Birth of a Nation, during National Action Network's action rally and radio broadcast Saturday.

According to a press release by NAN, Sharpton will question the “right-wing motives” of bringing up the 17-year-old rape case as a means to "perpetuate an all-white Academy Awards while obscuring exclusion of blacks."
