Israeli Ambassador’s “Cancer” Remark Against J Street Provokes Broad Jewish Leadership Rebuttal
5/21/2026, 10:41:30 PM
The Controversial Remark and Immediate Reaction
On Monday, Yechiel Leiter, Israel’s ambassador to the United States, described the liberal pro-Israel lobby J Street as “a cancer within the Jewish community” during remarks to the National Task Force to Combat Antisemitism. Within 24 hours, more than 500 rabbis, cantors and communal leaders signed a letter demanding that Leiter rescind the comment and issue a public apology. The signatories argued that such language “dehumanizes fellow Jews” and called for debate conducted with “humanity, humility and respect for the dignity of every Jew.”
Background: J Street’s Position and Prior Criticism
Founded as a progressive alternative to AIPAC, J Street bills itself as “pro-Israel, pro-peace, pro-democracy.” In recent months the group has opposed continued U.S. military aid to Israel and called for restrictions on arms sales, positions that have drawn ire from Israeli officials. Critics have previously likened the organization to extremist groups; former U.S. ambassador to Israel David Friedman called it “worse than kapos” in 2017.
Key Figures and Signatories
- Yechiel Leiter – Israeli ambassador to the U.S., longtime Netanyahu ally.
- Jeremy Ben-Ami – President of J Street, former U.S. State Department official.
- Michael Herzog – Former Israeli ambassador to the U.S., son of President Isaac Herzog.
- Jerrold Nadler (D-NY) – U.S. Representative, signatory.
- Dan Kurtzer and Tom Nides – Former U.S. ambassadors to Israel, signatories.
- Rabbi Rick Jacobs and Rabbi David Saperstein – Reform movement leaders, signatories.
- Jody Rabhan – CEO of the National Council of Jewish Women, signatory.
Additional opposition includes the Zionist Organization of America, which urged Jewish institutions to sever ties with J Street, and Sarah Lawrence College, which denied a student chapter application.
Data & Statistics
- > 500 Jewish leaders signed the apology demand.
- Signatories span political, religious and nonprofit sectors, illustrating broad cross-sectional concern.
Official Statements & Responses
J Street’s Ben-Ami called Leiter’s remarks “a shame” and warned that Israel “needs diplomats who open doors, not slam them in people’s faces.” He also noted that J Street has been “blacklisted” by the Israeli embassy since Leiter’s arrival. Leiter later condemned Minister Mai Golan’s anti-Reform remarks, describing them as “disgusting and reprehensible,” and announced plans to meet Reform leaders to apologize on Israel’s behalf. Michael Herzog tweeted that being pro-Israel requires “a clear line between criticizing Israeli government policies—and supporting anti-Israel agendas,” asserting that most Israelis view J Street as not pro-Israel.
Criticism & Opposition
The Zionist Organization of America called for Hillels, Jewish Community Relations Councils and federations to cut relations with J Street. Sarah Lawrence College’s student government rejected a proposal to establish a J Street chapter, citing concerns over the group’s stance.
Why It Matters
The dispute highlights tension between traditional pro-Israel advocacy and emerging progressive voices within the American Jewish community. It also tests the diplomatic rapport between Washington and Jerusalem, as ambassadorial language can influence congressional and public support for U.S. aid packages.
Conflicting Reports & Gaps
The Israeli embassy did not immediately respond to JTA’s request for comment, and J Street did not reply to a request for comment in the Times of Israel article. Consequently, the full scope of any planned reconciliation meetings remains unclear.
Verbatim Quotes
- “cancer within the Jewish community.” — Yechiel Leiter
- “It’s a shame, because Israel, right now, needs all the friends it can get, and it really needs diplomats who seek to open doors and not slam them in people’s faces,” — Jeremy Ben-Ami, J Street President
- “To me, to be pro-Israel is to draw a clear line between criticizing Israeli government policies — and supporting anti-Israel agendas and libels de-legitimizing the State of Israel,” — Michael Herzog
- “As an Orthodox Jew and as Israel’s representative to the United States I find her words disgusting and reprehensible, worthy of excoriation and rebuke,” — Yechiel Leiter (condemning Minister Mai Golan)
- “At this painful and polarized moment in Jewish life, leaders on both sides of the ocean bear a heightened responsibility to lower the flames rather than fan them further,” — Letter from signatories
What’s Next
Leiter has indicated he will meet Reform leaders in person to apologize, while J Street hopes the episode will reinforce the need for “embracing the diversity of opinion” within the Jewish community. Continued dialogue may shape future U.S. policy debates on Israeli aid and the broader discourse on what constitutes pro-Israel advocacy.
