John McGlone, a Christian minister, McGlone began visiting the University of Tennessee, Knoxville, in order to preach to students on open campus areas in 2008. In 2011, McGlone was told that he needed sponsorship by a student group, organization, staff, or faculty in order to be permitted to speak on campus. However, the policy was ambiguous as between requiring sponsorship by students or student groups. McGlone filed suit against various University administrators, alleging that the University’s sponsorship requirement was unconstitutionally vague.

Richard Hershey is a vegan activist who began to hand out leaflets on the main public walkway inside of Lehman College’s campus.

Hershey filed suit against various college administrators and public safety officers alleging that the college had violated his First and Fourteenth Amendment rights.

Gavin McInnes, a controversial far-right media personality, was pepper sprayed by non-student protestors while he was attempting to enter an event hosted by College Republicans at New York University (“NYU”).

Although this second protest was non-violent, it prohibited McInnes from continuing his talk. After twenty minutes of the continuous disruption, McInnes decided to cancel the event and leave campus.

A group of protestors—one wielding a cowbell—disrupted a College Republicans-sponsored presentation at Portland State University (“PSU”) by conservative journalist Michael Strickland. Whenever Strickland would attempt to speak, the protestor would begin yelling and ringing the cowbell continuously. Although a campus police officer was present, he did not intervene. After continuous disruption for an hour—the allotted time for the event—the protestor left, and the university allowed the event to continue for another thirty minutes. PSU later issued a statement defending the actions of the campus police officer, claiming that his inaction was justified “so as to not escalate a potentially unsafe situation.”

Pro-Trump protestors exercised their “heckler’s veto” by constantly interrupting and shouting insults at California Attorney General Xavier Becerra and California Assembly Majority Leader Ian Calderon at a public Q&A event hosted at Whittier College.

Apparently, the protest was organized to respond to Becerra’s lawsuit against the Trump administration’s decision to discontinue the federal DACA program.
