Graduation ceremonies will be held this weekend at colleges and universities across the United States, after weeks of protests in which more than 2,100 people were arrested on more than 40 college campuses in at least 25 states.

The wave of pro-Palestinian protests and university authorities' concerns about security have already begun to affect graduation ceremonies. In Michigan, protesters disrupted a graduation ceremony at the University of Michigan's College of Music, Theater and Dance on Friday, according to a video by a reporter from CNN affiliate Richmond Times-Dispatch.

The University of Vermont's president announced Friday that Linda Thomas-Greenfield, the U.S. ambassador to the United Nations, will no longer deliver the commencement address. Some protesters on campus had demanded that the university rescind its invitation to Thomas Greenfield.

All of this comes weeks after the University of Southern California decided to cancel its invitation to Asna Tabassum to speak at its ceremony. USC now plans to hold a “family graduation ceremony” on May 9, the school announced Friday, just over a week after canceling its main graduation ceremony.
