U.S. Secretary of Education Betsy DeVos was chosen to be the 2017 commencement speaker at Bethune-Cookman University, which is a historically black college.

Unfortunately, DeVos was not given a warm welcome Wednesday, as many students who oppose her views on education and school-choice were loud and disruptive during her address. Some of the students even stood up and turned their backs to the government official.

At one point, it got so bad that one of the university’s deans had to step in and issue a serious warning to the disrespectful students. Watch the clip above.
