( CNN ) The expulsions of two students by the University of Oklahoma for their role in a racist chant will likely not be the last word on the scandal . The Sigma Alpha Epsilon fraternity members can appeal the decision . More students might be expelled . And beyond the immediate issues around the now infamous incident , the university could experience a trickle-down impact for months , maybe years to come . Writing to the two students Tuesday , just two days after a video of frat members singing the racist song surfaced , OU President David Boren said they were being booted for `` leading a racist and exclusionary chant which has created a hostile educational environment for others . '' They were given until close of business Friday to contest the decision . No word yet on whether either will . CNN legal analyst Sunny Hostin said she believes there will be a constitutional challenge to the expulsions . `` It 's sort of one of the first things you learn in law school ... you may disapprove of what someone says but you still defend their right to say it , '' she said . Hostin added : `` I think there 'll be the arguments that these students were students , and that in our educational systems we want people to have , maybe , even a heightened level of freedom of speech . '' Also unknown at this point is whether other students who appear in the video will be expelled or otherwise punished . Already , the Greek letters sigma , alpha and epsilon have been removed from the frat house 's facade , the house will be closed as of midnight Tuesday and the university will board up the windows , following up on separate decisions by the university and the SAE national headquarters to shutter the Oklahoma chapter , Boren said . Sigma Alpha Epsilon is no stranger to scandal and sanctions . But he seemed to say that individual punishments could be a bit trickier . `` Well , legally , our concern is we have to demonstrate exactly how the educational experience of our students was threatened or disrupted by their actions , '' Boren said , `` and it really has to focus on the students on the bus . Did the other students have their educational experience disrupted ? '' While he unwaveringly declared `` there is no room for racists and bigots '' at his university , the very thing that could keep the SAE fraternity brothers Oklahoma Sooners is Title VI of the Civil Rights Act of 1964 . The law `` prohibits discrimination on the basis of race , color and national origin in programs and activities receiving federal financial assistance , '' but it also provides the parameters for determining if someone is violating the federal law , Boren said . Any punishment must be `` carefully directed '' if it 's to pass constitutional muster , although he made it clear he hopes some of the students involved wo n't wait for legal issues to be sorted out . `` I think some of the students themselves may take themselves off the campus , and I hope they do because this is not a place that wants racists , '' he said . So far , no students have dropped out -- voluntarily -- but the video has cost the university 's football team a top recruit as offensive lineman Jean Delance said Monday he was de-committing from the Sooners and considering other teams . It 's an issue that Ber Thaddeus Bailey , director of diversity , OU student government , worries about . `` I am concerned about the trickle-down effect from this incident , '' he said . `` I do want to encourage those who are considering the University of Oklahoma that this is a great place to study , and we are going to continue to progress . '' CNN 's Chris Cuomo contributed to this report .
