OU's Sigma Alpha Epsilon fraternity members have been allegedly implicated in a video showing members participating in a racist chant, and the fraternity is now under investigation.

The Daily received an anonymous tip about the video in an email Sunday evening. Shortly after, the video stirred up controversy online as OU students, including members of minority rights group Unheard, chastised the chant's racist language.

OU President David Boren has also spoken out against the men in the video in a statement and on Twitter. He said OU is conducting an investigation.
