Florida’s state university chancellor has ordered campus presidents to “take any necessary steps” to prevent disruption of graduation ceremonies by protestors.

The order covers the University of Florida, Florida State University, Central Florida University, Florida A&M University and eight others. Ten arrests were made at a pro-Palestinian rally at the University of South Florida on Tuesday after police deployed tear gas.

“We must protect the integrity of our commencement ceremonies and ensure the safety of our students,” Chancellor Ray Rodrigues wrote in a memo to presidents, adding that no ceremonies should be canceled or substantively modified. “These ceremonies are important milestones for our graduating students, and we owe it to our students to see to it that these ceremonies take place as planned. While we respect and honor the First Amendment, a commencement ceremony is not the time nor place to hold a political protest.”
