The University of Oklahoma has expelled two student fraternity members it says led a racist song caught on video. Members of Sigma Alpha Epsilon are seen on a bus singing a song that includes a racial slur and a vow that no black people will ever join their group. The school says the two students who allegedly led the song were expelled for creating “a hostile learning environment” and that all those involved “will learn … it is wrong to use words to hurt, threaten, and exclude.” Hundreds of students have marched at the school in a show of protest against racism. More on this story later in the broadcast.
