Graduation ceremonies will be held at colleges and universities across the United States this weekend, following weeks of protests that have seen more than 2,100 arrests on more than 40 campuses in at least 25 states.

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

The president of the University of Vermont announced Friday that U.S. Ambassador to the United Nations Linda Thomas-Greenfield will no longer deliver the commencement address. Some of the campus protesters called on the university to rescind the invitation to Thomas-Greenfield.

This comes weeks after the University of Southern California decided to rescind an invitation to Asna Tapas to speak at its ceremony. USC now plans to hold a “convocation family ceremony” on May 9, the school announced Friday, a week after canceling the main graduation ceremony.
