The chairman of the US House Committee on Education and the Workforce is demanding answers from the mayor of Evanston, Illinois, accusing him of failing to protect Jewish students during a pro-Hamas, anti-Israel encampment at Northwestern University that, lawmakers say. devolved into widespread antisemitic harassment and violence.

In a sharply worded letter dated Jan. 28, US Rep. Tim Walberg (R-MI) said Daniel Biss, a Democrat, refused to authorize Evanston police to assist when Northwestern requested help clearing the encampment in April 2024, despite reports of assaults, intimidation, and explicitly antisemitic incidents. Walberg wrote that the decision left the university unable to enforce the law safely, citing committee documents indicating Northwestern lacked sufficient police resources to carry out arrests without city support.

According to the letter, Jewish students reported being spat on, verbally harassed, and told to “go back to Germany” and “get gassed,” while others said they were called “dirty Jew” and “Zionist pig” as they attempted to move across campus. One student wearing a kippah reported being targeted, while another described being assaulted as an encampment member recorded the incident.

Walberg described the environment as a “hotbed of antisemitic harassment and hostility,” rejecting public characterizations of the encampment as peaceful.

Northwestern’s campus, located in Evanston, became a hub of anti-Israel activism following the Palestinian terrorist group Hamas’s Oct. 7, 2023, massacre across southern Israel, amid the ensuing war in Gaza. The school was ravaged by a series of antisemitic incidents tied to campus protests. Most notably, pro-Hamas activists illegally occupied the Deering Meadow section of campus in May 2024, demanding the university boycott all Israeli entities.

During the tense standoff in the spring 2024, Jewish students reported being physically assaulted and harassed while attempting to navigate campus, including incidents in which students wearing visible Jewish symbols such as a kippah were targeted.

Amid the post-Oct. 7 campus protests, the Education and Workforce Committee has been investigating several schools for what lawmakers described as insufficient responses to a surge in antisemitism. Last week, Walberg released documents along with his letter showing what he described as Biss’s failure to protect Northwestern’s Jewish students during the encampment.

Biss called Walberg’s letter a “dishonest political attack” during a news conference at City Hall on Thursday morning.

“But we are here today because that attack is an effort to go at the right to peacefully protest. This is an effort to use the very real danger of antisemitism to advance a political agenda,” Biss said. “I will say that personally, as a Jewish person, as a grandson of Holocaust survivors, I find it deeply, deeply offensive.”

Biss also defended his decision not to intervene in the campus unrest.

“After meticulously assessing the situation through the lens of public safety and the right to peaceful protest, we came to that conclusion,” Biss said. “We believed at the time it was the right decision. I believe today it was the right decision.”

The mayor added that the police department warned at the time that sending city officers to the encampment “might further inflame the situation.”

In May 2024, university president Michael Schill testified in front of the US Congress amid mounting skepticism over efforts to clamp down on campus antisemitism. His administration ultimately ended the encampment by reaching what became known as the “Deering Meadow Agreement” with the pro-Hamas protesters. Terms of the deal included establishing a scholarship for Palestinian undergraduates, contacting potential employers of students who caused recent campus disruptions to insist on their being hired, creating a segregated dormitory hall to be occupied exclusively by students of Middle Eastern and North African (MENA) and Muslim descent, and forming a new advisory committee in which anti-Zionists students and faculty may wield an outsized voice.

Biss touted the deal during his press conference last week, noting it ended the encampment peacefully.

However, the agreement was abolished in November 2025 as part of a deal that the university reached with the Trump administration, which months earlier in April had impounded at least $790 in frozen federal funds over accusations of antisemitism and other discriminatory behavior. Northwestern agrred to pay $75 million and implement measures to protect students from antisemitism in exchange for a resumption of federal funding.

However, the Council on American-Islamic Relations (CAIR) — an organization that has been scrutinized by US authorities over Hamas — filed a lawsuit on behalf of the Northwestern Graduate Workers for Palestine (GW4P) group to cancel Northwestern’s new antisemitism prevention course, which was implemented as part of the deal. The lawsuit was dropped last month.

In last week’s letter, Walberg alleged that political considerations influenced Biss’s decision not to intervene with police force. Walberg cited testimony from a Northwestern trustee who claimed Biss publicly framed his refusal to provide police support as a way to bolster his progressive credentials, even as the university struggled to maintain order. Internal communications referenced in the letter suggest Northwestern officials feared the city’s position left Jewish students vulnerable during a period of escalating campus unrest nationwide.

Walberg also criticized Biss for recently condemning the federal government’s agreement with Northwestern to restore funding, calling the mayor’s opposition inconsistent with his stated concern about discrimination.

The committee is requesting a formal briefing from Biss on law enforcement coordination and antisemitism in Evanston-area campuses, signaling potential legislative action. Walberg emphasized that Congress has broad constitutional authority to oversee education-related civil rights enforcement, including Title VI protections against religious and ethnic discrimination.

Biss has sought to bolster his reputation with the left flank of the Democratic Party as he runs for Congress himself in Illinois’ 9th District. The mayor has vowed to no longer accept funding from the American Israel Public Affairs Committee (AIPAC), the foremost pro-Israel lobbying group in the US, and has adopted a platform critical of the Jewish state.

In a campaign news release on Thursday, Biss wrote that Walberg’s letter was a “baseless attack fueled by” AIPAC.

“It’s no coincidence that Rep. Walberg’s letter arrived just eight days before the beginning of early voting in the March primary election,” Biss wrote. “They’re playing cheap political games in service to AIPAC’s right-wing agenda. It is shameful.”

AIPAC’s mission is to foster bipartisan support in Congress for the US-Israel alliance.

Spectators suggest that Biss, who is facing a bruising primary battle with 26-year-old anti-Israel social media personality Kat Abughazaleh, has sought to curry favor with local progressive activists by pushing a harder line against the Jewish state.
