Simone Zimmerman
Simone Zimmerman’s Participation in the Pro-Hamas Encampment at Columbia University (Columbia)

Zimmerman was suspended from her position as the Jewish outreach coordinator for presidential candidate Bernie Sanders, in 2016. Zimmerman co-founded the anti-Israel group IfNotNow (INN) in 2014. She has participated in anti-Israel activist trips, expressed support for violent protesters and led protests against the American Israel Public Affairs Committee (AIPAC).
Zimmerman has also spread hatred of Israel and America, smeared Holocaust survivor Elie Wiesel, demonized American Jewish organizations and opposed the recognition of Jerusalem as Israel’s capital.
Zimmerman has condemned the Birthright Jewish heritage tour and is a supporter of the Boycott, Divestment, Sanctions (BDS) movement.
As a national leader of INN, Zimmerman either made the decision or was complicit in INN’s decision to partner with the anti-Semitic American Muslims for Palestine (AMP).
Zimmerman reportedly graduated from the University of California, Berkeley (UC Berkeley) with a bachelor’s degree in Middle Eastern studies in 2013.
Zimmerman was reportedly the founder of the J Street U chapter at UC Berkeley and was elected national president of J Street U for the 2012-13 school year.
As of July 2019, Zimmerman was the Director of B'Tselem USA, since March 2019.
Suspension from Presidential Campaign
In April 2016, Zimmerman was appointed to serve as the Jewish outreach coordinator for the Bernie Sanders 2016 Presidential campaign.Zimmerman’s appointment sparked controversy after a March 2015 Facebook post she wrote was discovered, in which she reportedly wrote: “F*** you, Bibi, for daring to inisist that you legitimately represent even a fraction of the Jews in this world…for pushing Israel, in word and deed, farther away from the international community, and…trying to distract the world from the fact that you sanctioned the murder of over 2,000 people this summer.”
Israel commenced Operation Protective Edge (OPE) in July 2014, to stop rocket fire targeting Israeli civilians and to destroy Hamas attack tunnels.
Throughout the summer of 2014 — during Operation Protective Edge (OPE) — Hamas's deployment of human shields was extensively documented and publicized. Hamas encouraged Gazans to act as human shields to frustrate Israeli efforts to avoid civilian casualties in Gaza.
On April 14, 2016, two days after being appointed, Zimmerman was suspended from the position, due to her 2015 profanity-laced Facebook post against Israeli Prime Minister (PM) Benjamin Netanyahu.
Following Zimmerman’s suspension, INN published a statement blaming Zimmerman’s dismissal on a “smear campaign waged against her” and describing her removal as “just the most blatant example of the American Jewish establishment trying to intimidate and silence young people acting on the very same Jewish values of Tzedek (Justice) and Tikkun Olam (reparing [sic] the world).”
Activist Trips to Israel
In February 2018, Zimmerman was one of a number of INN and All That’s Left activists who reportedly delivered letters of solidarity with Ahed Tamimi to Tamimi’s father Bassem, at his home.Zimmerman reportedly told Bassem: “Ahed’s story has really moved a lot of people. Of course she’s a symbol, but she’s also just a person who deserves to have the future that she wants to have.”
Bassem Tamimi has exploited young children as political props in staged confrontations with Israeli soldiers. In 2011, he was jailed for organizing violent rallies and inciting minors to commit violent crimes such as rock-throwing.
On May 20, 2017, INN shared a photo on Facebook of Zimmerman in a delegation to Israel comprised of INN and Center for Jewish Nonviolence (CJN) activists.
A May 19, 2017 article showed that the delegation met with Issa Amro, the head of the Youth Against Settlements (YAS) movement who is known for vandalism and attacking Israeli soldiers in Hebron. Amro has been charged with numerous acts of violence against Israeli civilians and security forces.
The delegation also met with anti-Israel activist Sam Bahour, who shared a Facebook photo on May 12, 2017, with Zimmerman and her fellow INN activists. Bahour has equated Israel with Nazi Germany, expressed support for terrorists and worked with anti-Israel propagandists, including Students for Justice in Palestine (SJP) activists.
Supporting Violent Protesters
On May 15, 2018, Zimmerman tweeted: “If Israeli leaders wanted to de-escalate in Gaza, they could have. But the truth is that the violence benefits them. They can pop champagne w their fanatic, racist friends, party to eurovision soundtrack, & blame those backwards animals for not valuing life like us civilized folk.”On May 16, 2018, a Hamas senior official, Salah al-Bardawil, stated that 50 out of 62 protesters killed during the May 14 Gaza border protest were Hamas operatives. Palestinian Islamic Jihad (PIJ) also claimed that three of its members were killed at the same protest.
Most of the Gazans who died between March 30 and April 6, 2018, were identified as terror operatives who were killed while carrying out terrorist attacks, rioting against IDF forces or attempting to breach the border fence between Israel and the Gaza Strip.
Protesting AIPAC
On the same day, INN organizers claimed on Facebook that AIPAC's invitation to the U.S. President revealed AIPAC was “more invested in the politics of hate than in a vision of a peaceful Middle East.”
On March 20, 2019, Zimmerman tweeted: “No, AIPAC is an outdated establishment pushing uncritical support for Israeli occupation & trying to stifle the robust conversation about how it threatens safety & freedom of Palestinians & Israelis alike. Leaders who want to be viewed as relevant in this shifting space get that.”
Hatred of Israel
On November 30, 2018, Zimmerman tweeted: “As long as the idea that Palestinians should be free from the river to the sea continues to be understood by Jews as a direct threat to our safety, we are setting ourselves up to lose.& We will never be truly free.”“From the River to the Sea, Palestine will be Free” is a chant used [00:02:47] to call for the elimination of the State of Israel. It has also been employed by Hamas leader Khaled Mashal to call for the replacement of Israel with an Islamic state. In April 2024, the U.S. House of Representatives passed a resolution condemning the chant as antisemitic.
On July 19, 2018, Zimmerman tweeted: “Prediction: 2018 will be remembered as the year it became mainstream to call Israel an apartheid state.”
On July 17, 2018, Zimmerman tweeted: “Running out of creative words to describe the cruelty of Israeli policy towards Gaza's 2 million residents. Trying to suffocate, starve, and push a civilian population already deep in a humanitarian disaster over the edge. Inhumane and terrifying.”
On July 15, 2018, Zimmerman tweeted: “In case it was unclear: Israel holds the keys. It is Israel that keeps the people of Gaza locked in an open air prison. It is Israel denying them basic rights and needs. And it is the people of Israel who will also sadly pay the price for their leaders cruelty & idiocy.”
On June 14, 2018, Zimmerman praised on Twitter a Forward article titled: “How Israel Killed Liberal Zionism,” that she described as “calling on Liberal Zionists to fight Israel's formalization of apartheid.”
On July 10, 2018, Zimmerman tweeted: “The world cheered on the rescue of 13 young people trapped & nearly suffocated in Thailand cave by a natural disaster. The world is indifferent as Israel traps & slowly suffocates over 1 million young Palestinians through inhumane closure policies in Gaza, a man-made disaster.”
On May 15, 2018, Zimmerman tweeted: “& amazingly, people still buy it. 70 years of dispossession.50 years of military occupation. 10+ years of siege on Gaza. & some still believe that Israel can kill Palestinians because they are threatening our right to exist. Who is threatening whose existence here? #Nakba70.”
The term “Nakba” is generally translated as “catastrophe” in Arabic, referring to the outcome of the 1948 Arab-Israeli War. It is a term used to delegitimize the creation of the State of Israel by drawing a comparison to the Holocaust, known in Hebrew as the Shoah, meaning “catastrophe.”
On December 7, 2017, Zimmerman tweeted: “I'm tired of people claiming to support two states as a way of whitewashing the fact that they are giving tacit support for apartheid.”
On November 10, 2015, Zimmerman tweeted about Israeli PM Benjamin Netanyahu attending the Jewish Federations of North America (JFNA)’s annual General Assembly (GA). Zimemrman wrote: “Netanyahu has made Israel the most dangerous place to live as a Jew today. Does not deserve such unquestioning welcome at #JFNAGA.”
On February 29, 2016, Zimmerman published an article in Haaretz, in which she wrote: “No public relations trick can save Israel’s image. The problem isn’t with the hasbara. The problem is nearly 50 years of occupation. The problem is rampant racism in Israeli society.”
Spread Hatred of America
Zimmerman reposted a February 4, 2025 post on X that said: “Clearly dude doesnt know what ethnic cleansing is bc Harris fully endorsed the making Gaza uninhabitable, the concentration of Palestinians in the south, their denial of safe quarter, and their starvation for the purpose of ethnically cleansing them.Trump took the US’s mask off.”Smearing Holocaust Survivor Elie Wiesel
Three days after the death of Holocaust survivor and founding chairman of the U.S. Holocaust Memorial Museum, Elie Wiesel, Zimmerman co-authored a Haaretzarticle that claimed: “Wiesel represented not only his generation’s greatest triumph, but perhaps also its greatest failing. As Wiesel demanded we set ourselves apart, he closed his eyes to reality and denied Palestinian suffering.”Zimmerman and her co-author also accused Wiesel of working “to further a violent religious nationalist agenda” and condemned “his fierce opposition to the hard truths in the Goldstone report.”
The Goldstone Report was the controversial product of a 2009 United Nations Fact-Finding Mission, sent to investigate Operation Cast Lead.
Israel commenced Operation Cast Lead (OCL)in 2008-09 in order to stop Hamas rocket fire from Gaza targeting Israeli civilians. In 2010, Hamas admitted that nearly 700 of the Palestinian casualties in OCL were combatants.
Following widespread criticism and rejection of the report for its “methodological failings, legal and factual errors, and falsehoods,” Judge Richard Goldstone, who authored the report, expressed “regrets about his report” and retracted its central thesis.
Demonizing American Jewish Organizations
On February 22, 2019, Zimmerman tweeted: “Every day, they [American Jewish organizations] are silent about the violent, undemocratic regime that Israel maintains over Palestinians and at the horrifying levels of incitement against Palestinians and Israeli human rights defenders- including threats to their lives- that is commonplace in the Knesset.”On October 21, 2018, Zimmerman wrote an article demonizing the American Jewish community. Zimmerman said that “American Jewish dollars embitter Palestinian lives...entrench the occupation” and that “Jewish establishment organizations fund the dispossession of Palestinians...Israel’s march toward full-blown apartheid.”
On May 14, 2018, Zimmerman tweeted in response to the Anti-Defamation League (ADL), celebrating the opening of the U.S. embassy in Jerusalem: “The Jewish establishment, incl @ADL_National, will be remembered for welcoming in Israeli apartheid, celebrated & decorated in Jerusalem, and maintained by killing masses of Palestinian protesters in Gaza and colonization of West Bank. Historic shonda.”
On April 28, 2018, Zimmerman tweeted: “The ADL does not deserve the honor of being called a civil rights organizations when it routinely defends Israel for violating basic rights and supports denial of rights from anyone who dissents against Israel’s unjust policies- here are just a few examples..”
Opposing the Recognition of Jerusalem as Israel’s Capital
On May 14, 2018, Zimmerman tweeted regarding the U.S. government’s decision to move the U.S. embassy to Jerusalem: “What moving the embassy means is a US stamp of approval on Israel erasing Palestine. No Palestinian flags = no legitimate Palestinian claims to this place.”On the same day, Zimmerman tweeted: “Outraged. Horrified. Mourning.Jewish liberation cannot and will not ever come at the expense of the Palestinian people. While hateful leaders open the Embassy of Occupation in Jerusalem today, you can join @IfNotNowOrg today to build #EmbassyofFreedom.”
Zimmerman’s tweet included a link to an INN petition opposing the embassy move. The petition stated that “over the last several months, Trump and Netanyahu have abused and manipulated every opportunity in the region to provoke conflict, and we refuse to let them do so in the name of American Jews.”
The petition also promoted an INN protest in Washington, D.C., titled: “The #EmbassyOfFreedom: Rally Against Israeli Violence on Gaza.” The Facebook event description said the aim of the action was “to make it clear that the future of the Jewish community is opposed to that disastrous decision” to move the U.S. Embassy to Jerusalem.
On December 7, 2017, Zimmerman tweeted: “If you support #jerusalem move, you don't support two states. It's time 2b clear if you're on the side of apartheid or equal rights for all.”
Condemning Jewish Heritage Tour
On July 17, 2018, Zimmerman tweeted in support of INN activists who had walked off their Birthright trips: “Doesn't matter if it [Birthright] pre-dates them. It is currently used by the state to advance a political agenda- Jewish engagement in the name of defending Israel, fighting BDS etc- while erasing violence towards Palestinians. Given that I support disrupting BR through boycotts and walkoffs.”Birthright Israel is a heritage trip to Israel for Jewish young adults from across the world.
On July 15, 2018, multiple INN activists joined and then staged a walk-off in protest from a Birthright tour of Israel. INN posted a photo of the activists on Instagram and wrote: “Birthright wouldn’t show the reality and complexity of the Occupation, so earlier today 8 young Jews walked off 2 trips to go find the truth for themselves.” The activists claimed (00:00:01) Birthright trips were “like visiting the South in the 1950s and not talking about Jim Crow segregation.”
On June 28, 2018, Zimmerman tweeted: “Birthright, consider this a warning: our generation is too smart to continue eating up your propaganda. Taglit is #NotJustAFreeTrip. It is an intentional part of the infrastructure meant to whitewash the occupation and to keep our community indifferent to human rights violations.”
As part of the campaign, INN activists joined and then staged walk-offs in protest on Birthright trips. INN also organized a demonstration against Birthright, the demonstration’s Facebook description said INN was giving Birthright “one final chance to choose between the demands of INN members and their current policy.”
Participation in the Pro-Hamas Encampment at Columbia
On April 22, 2024, Zimmerman posted on X a photo from the pro-Hamas encampment at Columbia and wrote: “Spent the first night of Passover at the student seder in the Gaza solidarity encampment at Columbia. / The Jewish flank of the Palestine solidarity movement is growing and it is so beautiful to behold…”The encampment also supported the Boycott, Divestment, Sanctions (BDS) movement. Columbia is located in New York, New York.
On April 19, 2024, Zimmerman posted on X photos from the encampment and wrote: “Tonight at Columbia Jewish students led a full Shabbat service at the Gaza solidarity encampment. Minutes later Muslim students had their evening prayer service. All surrounded by love…”
On April 17, 2024, Columbia students and anti-Israel activists set up a pro-Hamas “Gaza Solidarity Encampment” on the university's main lawn. Many participants were arrested and the encampment featured multiple violent incidents, including taking over a campus building and taking a university worker hostage.
Activists protested Israel’s war against Hamas and demanded that Columbia “divest from companies and institutions that profit from Israeli apartheid, genocide and occupation…”
The action had reportedly been planned for months and was organized by the Columbia University Apartheid Divest (CUAD) coalition. The encampment was also organized by Columbia’s banned pro-Hamas activist group Students for Justice in Palestine (SJP) and the university chapter of Jewish Voice for Peace (JVP). Activists reportedly received training from National SJP and other anti-Israel organizations.
Among the encampment leaders was Columbia student Khymani James who had said [00:00:25]: “Zionists…They are nazis!... They’re supporters of genocide! Why would we want people who are supporters of genocide to live?... Be glad, be grateful that I am not just going out and murdering Zionists.” Aidan Parisi, another encampment leader, responded to Columbia’s demand to disband the encampment by declaring online that: “COLUMBIA WILL BURN.”
The encampment was forcibly dismantled at the directive of Columbia’s president and administration. The NYPD [New York Police Department] entered the area, cleared the encampment and arrested more than 100 protestors, approximately 80 of whom were Columbia students. The students were charged with trespassing and suspended from Columbia indefinitely.
The next day, activists created a new encampment. When divestment negotiations with Columbia failed, protesters illegally forced their way into the university’s Hamilton Hall on April 30, 2024. They smashed [00:00:55] through a glass-paneled door, broke security cameras, threw university property out of the windows and unfurled [00:00:01] a banner in the building’s wall that read: “INTIFADA,” a term in Arabic for uprising or insurrection that carries the connotation of violence.
While barricading themselves in the building, agitators kept three Columbia custodians hostage and stopped them from leaving. When the NYPD raided and dismantled the encampment a second time, they arrested more than 100 students, nearly half of whom were reportedly not affiliated with Columbia.
NYPD shared on Twitter photos of objects the police found in Hamilton Hall. These included knives, hammers, gas masks, ropes and a pamphlet that read [video 1]: “...DISRUPT/RECLAIM/DESTROY zionist business interests everywhere! DEATH TO ISRAELI REAL STATE! DEATH TO AMERICA!...LONG LIVE THE INTIFADA!”
Just outside the encampment area, Jewish students were called [slide 2]: “Uncultured a** b**ches!” and were told to “Go back to Europe!” Activists also said [slide 3] to them: “Yahoodim [Jews], yahoodi [Jew], f**k you!” and “Stop killing children!” as they walked from campus to their dorm rooms.
Also just outside the encampment area, anti-Israel activists chanted [slide 5]: “Ya Hamas, ya habib, odrob, odrob Tel Aviv! [Oh Hamas, oh loved one, strike, strike Tel Aviv!]”, a chant that celebrates Hamas rocket attacks against Israel.
An activist just outside the encampment area held [photo 4] a sign that said, referring to the Izz ad-Din al-Qassam Brigades, Hamas’s military wing: “AL-QASAM’S NEXT TARGETS.” Her sign contained an arrow pointing to a pro-Israel crowd.
On May 31, 2024, Columbia SJP announced that its activists had set up a third encampment at the university. At the encampment, protesters reportedly displayed on a big screen a video that portrayed Hamas as a peace-seeking organization and made a sign that contained an inverted red triangle, a symbol in support of Hamas.
The Columbia encampment reportedly inspired a wave of protest encampments across North American campuses, where pro-Israel students were blocked or restricted from campus facilities. Jewish students were reportedly harassed in several other ways.
BDS
The Boycott, Divestment, Sanctions (BDS) movement was founded by Omar Barghouti in 2005 to challenge “international support for Israeli apartheid and settler-colonialism.” BDS is an allegedly “Palestinian-led movement,” although leading BDS activists have admitted [00:01:01] this is not true.
One of the demands of BDS includes [point 3] what is generally known as the “right of return,” a demand discredited as a way to eliminate Israel. Barghouti said the “right of return” is a means to “end Israel’s existence as a Jewish state.”
Barghouti has said that BDS “aims to turn Israel into a pariah state, as South Africa once was.”
In his activism, Barghouti has also said [00:05:55] regarding Israel: “Definitely, most definitely, we oppose a Jewish state in any part of Palestine. No…rational Palestinian, not a sellout Palestinian, will ever accept a Jewish state in Palestine.”
The movement has been linked to numerous terrorist organizations and received a public endorsement from Hamas in 2017.
BDS initiatives include calling on institutions and individuals to divest from Israeli-affiliated companies, promoting academic and cultural boycotts of Israel, and organizing anti-Israel rallies, protests and campaigns.
The movement’s most notable achievement has been the infiltration of university campuses through lobbying for “BDS resolutions.” In these cases, student governments and student groups, backed by their own anti-Israel members and affiliates, have proposed resolutions on some form of boycott of, or divestment from, Israel and Israeli-affiliated entities.
Boycott resolutions, although non-binding, have been passed by student governments on numerous North American campuses.
BDS activity is often aggressive and disruptive. It has been noted that universities that pass BDS resolutions see a marked increase in anti-Semitic incidents on campus. On one campus, when the student government debated a BDS resolution, reports emerged of violent threats against those opposing it.
IfNotNow (INN)
INN claims to be “young Jews angered by the overwhelmingly hawkish response of American Jewish institutions” to OPE. INN presents three demands on its website: “Stop the War on Gaza, End the Occupation, and Freedom and Dignity for All.”
INN defines “the Occupation as the military rule over Palestinians in the West Bank, East Jerusalem, and Gaza,” which is land Israel has controlled for nearly 50 years since the 1967 Six-Day War. However, INN leaders have made [00:34:32] the claim [00:13:49] at protests that the occupation is 70 years long, referring to Israel’s founding in 1948.
INN actions have aimed to demonize [00:38:13] Israel, harass [00:05:44] mainstream American Jewish organizations like the Anti-Defamation League (ADL) and decrease support for Israel among American Jews.
INN has used “public action and imaginative ritual” to achieve its goals, including disruptions where activists were arrested.
One of the high-profile arrests occurred at a May 2018 disruption at a U.S. Senator’s office in Washington, D.C. to protest legislation against the Boycott, Divestment, Sanctions (BDS) movement.
At the same incident, INN used [00:07:17] the Jewish ritual of the Mourner’s Kaddish prayer to mourn [00:09:10] protesters who were killed during the Hamas-organized and funded Great March of Return riots on the Israel-Gaza border.
INN activists have also staged and promoted walk-offs from Birthright Israel trips, a heritage trip to Israel for young Jewish adults from across the world.
INN claims to take no position on the BDS movement and that it is “open to any who seek to shift the American Jewish public away from the status quo that upholds the Occupation.” However, INN organizes with pro-BDS, anti-Israel organizations including American Muslims for Palestine (AMP) and Jewish Voice for Peace (JVP).
