Ann Arbor Police are investigating after vandals attacked the home of University of Michigan Provost Laurie McCauley, busting out windows and scrawling antisemitic graffiti.

Police spokesman Chris Page told the Detroit Free Press officers were called to the home around 8 a.m. on Sunday and “discovered an object had been thrown through a bedroom window.”

Other vandalism included the words “Free Palestine,” “Divest” and “No Honor in Genocide” spray painted on the front of the home, he said.

No one was injured in the attack, which police believe occurred some time after 9 p.m. Saturday. It remains unclear whether anyone was home at the time, according to the Free Press.

The ordeal is the latest in a series of similar attacks targeting the homes and businesses of UM officials as part of an ongoing campaign to pressure the university to divest from Israel and companies that support the country’s defense against Hamas terrorists.

Vandals attacked the Huntington Woods home of Jewish UM Regent Jordan Acker in December, hurling a jar of urine through a window and spraying anti-Semitic graffiti on a vehicle, according to The Detroit News.

Acker noted an upside-down triangle that was scrawled in red spray paint on his wife’s SUV “has been used by Hamas to mean something is a legitimate military target.”

“This is a threat,” said Acker, who was home with his wife and kids during the attack, told The News. “This was not a protest. This is terrorism.”

The December attack followed another at Acker’s Southfield law office in June, when the firm’s sign was defaced with “Free Palestine,” “Divest now,” “F***You Acker” and “UM Kills,” and its doors painted with red handprints.

In May, more than 30 masked vandals staged demonstrations at the private residences of multiple regents, where they erected tents, and littered lawns with fake corpses in blooded sheets, bloodied toys, and other garbage.

“The University of Michigan condemns these criminal acts in the strongest possible terms,” UM said in a statement following the December attack on Acker’s home. “They are abhorrent, and unfortunately, just the latest in a number of incidents where individuals have been harassed because of their work on behalf of the university. This is unacceptable and will not be tolerated. We call on our community to come together in solidarity and to firmly reject all forms of bigotry and violence.”

The situation has fueled civil rights complaints from both Jewish and Muslim at UM, with both claiming the school has failed to protect their federal Title VI rights, which prohibits discrimination based on race, color or national origin.

Allegations of antisemitic harassment and discrimination were cited in a letter from Secretary of Education Linda McMahon sent to 60 schools, including UM, warning university officials to better protect Jewish students or face enforcement actions, the Detroit Free Press reports.

“The department is deeply disappointed that Jewish students studying at elite U.S. campuses continue to fear for their safety amid the relentless antisemitic eruptions that have severely disrupted campus life for more than a year,” McMahon wrote.

The letter followed three days after Trump administration canceled $400 million in grants for Columbia University and five days before the arrest of Columbia University pro-Palestinian student activist Mahmoud Khalil over his alleged support for Hamas.

Khalil was arrested by ICE at his university apartment on March 8 following President Donald Trump’s promise to remove foreign students who terrorized college campuses across the country last year in protest of Israel’s defense against Hamas.

Tricia McLaughlin, spokesperson for the Department of Homeland Security, told The Associated Press Khalil “led activities aligned to Hamas, a designated terrorist organization.”

The AP described Khalil, who finished a master’s degree in international affairs last semester, as “a negotiator for students as they bargained with university officials over an end to the tent encampment erected on campus last spring.”

“Khalil was also among those under investigation by a new Columbia University office that has brought disciplinary charges against dozens of students for their pro-Palestinian activism, according to records shared with the AP.”

Similar protests took place in Michigan, where Jewish Democratic Attorney General Dana Nessel drew insinuations of bias from U.S. Rep. Rashida Tlaib, D-Detroit, when the AG announced charges against 11 pro-Palestinian protestors at the University of Michigan in September.

Tlaib, the only Palestinian in Congress and a participant in the UM protests, is among more than a dozen Michigan lawmakers and elected officials now calling on U.S. Department of Homeland Security Secretary Kristi Noem to release Khalil from ICE detention, Michigan Advance reports.

Activists aligned with that effort descended on University of Michigan President Santa Ono’s home last weekend to decry the “abduction” of Khalil and urge officials to push back on Michigan Attorney General Nessel’s criminal case against student activists.

“We fight back because we know that both our legal battles and the abduction of Mahmoud are not just about legality or even just about freedom of speech,” UM student Eaman Ali told the Advance. “We fight back because we know Mahmoud was not just abducted because he is an immigrant. He was abducted because he’s Palestinian. He was abducted because his very existence undermines the legitimacy of the settler colonial project of Israel.”

The incessant protests, however, have only strengthened UM’s ties to Israel, as Ono noted during a forum on antisemitism hosted by the Anti-Defamation League earlier this month.

Not only did the UM Board of Regents reject calls to divest money from its $17.9 billion endowment in Israeli companies, they opted to increase that investment based on financial factors, The Detroit News reports.

“My response, and the board’s response, to this whole to divest, or cut those relationships, was to actually invest even more,” Ono said. “The three of us have put more money into it, and great things have come out of these relationships and more things will come in the future.”
