(The Lion) — Harvard University recently took action against an anti-Israel protester.

The Massachusetts school condemned and fired one of its employees for taking down a poster on campus featuring Israeli hostages.

Harvard’s chief diversity and inclusion officer, Sherri Charleston, sent staff a letter last week denouncing the act “in the strongest possible terms.”

The employee in question was Jonathan Tuttle, a cataloguer at the Radcliffe Institute’s Schlesinger Library.

Someone filmed Tuttle tearing down a poster showing Israeli hostages during a Harvard Out of Occupied Palestine rally. The poster showed the faces of the Bibas children, two Israeli citizens taken hostage by Hamas militants during the Oct. 7 attacks.

By Sunday, Harvard had removed Tuttle’s name and contact information from the Schlesinger Library’s website.

School spokesperson Jason Newton told the Harvard Crimson that the “Harvard employee involved in an incident during a protest last week is no longer affiliated with the University.”

Tuttle violated Harvard’s Campus Use Rules by removing the poster, said Charleston. The rules, released in August, prohibit “tampering with or removing” approved displays.

Radcliffe Institute Dean Tomiko Brown-Nagin reiterated Charleston’s sentiment.

In an open letter to Radcliffe faculty, Brown-Nagin said she supports everyone’s right to protest, but Tuttle’s actions were improper and ultimately suppress the free speech of others.

“Disruptive behaviors—including property destruction or defacement and acts of vandalism that seek to suppress or censor the speech of others—are not protected speech,” she wrote. “They are behaviors that constitute misconduct; they violate multiple Harvard and Radcliffe rules and may also be punished under criminal law.”

Tuttle’s firing comes as schools nationwide face increased scrutiny over anti-Israel protesters on college campuses.

Earlier this month, a federal task force said it would investigate antisemitism on 10 college campuses, including Harvard.

The Trump administration also announced last week it would cut $400 million in federal grants, mostly for medical and scientific research, to New York’s Columbia University over allegations of antisemitism on campus.

Hamas waged war on Israel on Oct. 7, 2023, killing around 1,200 people and kidnapping over 240 in a surprise attack, including American citizens. The two sides have been at war ever since, although there is a current ceasefire. Israeli Prime Minister Benjamin Netanyahu has said destroying Hamas is his country’s goal.
