Hours after a video of purported University of Oklahoma fraternity members chanting racist slogans was leaked on Sunday night, hundreds of OU students gathered on the school's North Oval on Monday morning (March 9) to demonstrate against the Sigma Alpha Epsilon chapter.

After joining a silent walk through the Student Union with demonstrators, University president David Boren addressed the early morning gathering, calling the language in the video "reprehensible" and sending a stern warning to any OU students who abuse their free speech privileges in that way.

"You're disgraceful, you have violated every principle that this university stands for," he said.

The gathering followed a Sunday night prayer vigil, during which students spoke about how the video impacted them and asked forgiveness for the people involved in making the clip.

The school's newspaper, The Oklahoma Daily, reported that some fraternity members were seen exiting the house with suitcases late Sunday night, and at 12:15 a.m., it appeared that someone had spray-painted "Tear it Down" on the side of the SAE house. An unnamed member reportedly told the paper that some SAE brothers had received email death threats and threats on their Facebooks accounts.

In the clip, which was anonymously sent to the student-run Daily newspaper on Sunday, fraternity members can be heard singing, "There will never be a n----r SAE. You can hang him from a tree, but he can never sign with me." According to CNN, the Daily received the nine-second video less than 24 hours after SAE marked its 159th annual Founder's Day celebration.

A spokesperson for SAE could not be reached by MTV News for further comment at press time. Boren announced that SAE is banned from campus and all members must move out of their house by midnight on Tuesday. At a press conference on Monday morning he reiterated that such racist behavior is "intolerable," saying that it has no place on the OU campus and will not have one as long as he is leading the university.

Among the spontaneous protests against the fraternity -- which was immediately shut down by its parent organization Sunday night -- was the posting of hundreds of sticky notes on the door of the Student Affairs office in Oklahoma Memorial Union listing student grievances.

A second video purporting to show a different angle of the original was posted on Sunday night. In it, the same racist chant is heard, with one man stepping forward near the end in what appears to be an attempt to stop the song.

Nearly two months ago, the campus group behind Monday's protest, Unheard, released an open letter on Facebook addressing some minority students' grievances. The alliance of black OU students said their focus was on the lack of black faculty outside of the African-American studies department, retention rates, financial assistance/scholarships and supportive programs for black students and a plea for equitable funding for black student organizations.

"The student body demands the administration to take action in creating a culturally inclusive and aware campus environment," read the "Needs and Solutions" section of the letter from Unheard, which was formed in response to the police shooting of Michael Brown in Ferguson, Missouri.
