Mamdani rolls back Adams’ executive actions on antisemitism, deletes posts from official record on first day in office

He also canceled other Adams-era initiatives, including a directive instructing the NYPD to reassess its handling of protests at houses of worship, a measure Adams introduced after anti-Israel activists violently targeted a New York City synagogue. The socialist mayor also deleted tweets from the official New York City Mayor’s X account about combating antisemitism.

The move has ignited sharp criticism from Jewish advocacy groups and confirmed critics' doubts about whether Mamdani’s administration will fight antisemitism, given the mayor’s history of antisemitic and anti-Israel comments and actions.

On his first day in office, Mamdani signed the executive order nullifying those of Adams since September 26, 2024, the date Adams was indicted on corruption charges by the Biden administration. Those charges were later dismissed by the Trump administration after Adams claimed he was being politically prosecuted. Mamdani’s campaign framed the revocation as a governance reset meant to ensure “a fresh start for the incoming administration.”

The broad scope of the repeal immediately drew attention, because it included several high-profile executive actions tied to antisemitism and Israel, especially Adams’s adoption of the International Holocaust Remembrance Alliance (IHRA) working definition of antisemitism. Adams had embraced the IHRA definition, which states that some forms of criticism against Israel are antisemitic, including claims that deny the Jewish people the right to self-determination or characterize Israel’s existence as inherently racist. The definition has been adopted by governments and institutions worldwide.

For Mamdani, a far-left mayor who has repeatedly refused to recognize Israel’s right to exist as a Jewish state, refused to condemn the phrase “Globalize the Intifada,” and has described himself as anti-Zionist, the IHRA definition conflicts with his anti-Zionist rhetoric. Mamdani’s executive order also nullified a directive opposing the campaign to boycott Israel, a significant change given Mamdani’s long history of supporting the antisemitic Boycott, Divestment, and Sanctions (BDS) movement.

Another casualty of the rollback was Adams’s New York City–Israel Economic Council, a group established to strengthen business ties between New York and Israel.

Mamdani did not eliminate the Mayor’s Office to Combat Antisemitism, which Adams established in May. Mamdani’s Executive Order No. 2, which outlines the structure and functions of his administration, indicates the antisemitism office will remain and includes a description of its responsibilities that appears consistent with how it operated previously. The office’s director, Rabbi Moshe Davis, a close aide to Adams, said Wednesday he had not received guidance from Mamdani’s transition team and did not know whether he would remain in his position.

Mamdani also drew immediate backlash after past posts about combating antisemitism were removed from the official @NYCMayor X account, according to the National Jewish Advocacy Center. The group slammed Mamdani in a letter, warning that deleting official posts addressing Jewish safety, especially on his first day, sends a troubling message at a moment of heightened antisemitic intimidation and violence. “It is difficult to overstate how disturbing it is that one of your very first acts… was to delete official @NYCMayor tweets addressing the protection of Jewish New Yorkers,” the letter said. The group argued that the mayoralty is a civic institution and not “a social-media account to be curated for convenience or optics.”

The letter was also sent to the city’s Department of Investigation and the Conflicts of Interest Board, raising a legal concern: social media posts from official accounts are public records, and deleting them without proper archiving could violate city rules. Mamdani spokesperson Dora Pekec said in a statement to The New York Post, “The Mayor remains steadfast in his commitment to root out the scourge of antisemitism in our City,” adding that Mamdani intends to renew the antisemitism office and dramatically increase funding for the Office for the Prevention of Hate Crimes.

In one of his last acts in office, Adams posted a thread highlighting what he called the city’s “first-ever municipal report” on fighting antisemitism, describing it as a blueprint for 2026. After Mamdani took control of the account on Thursday, two posts in that thread were missing, leaving only the final message visible, accompanied by notices stating, “This post was deleted by the post author.”

The Democratic Socialist and first Muslim to lead City Hall has faced ongoing scrutiny for his anti-Israel advocacy and his ties to figures associated with radical anti-Zionist groups. He has previously vowed to arrest Israeli Prime Minister Benjamin Netanyahu as a war criminal if he enters New York City.

An Anti-Defamation League (ADL) report released last week pointed to ties between some Mamdani appointees and anti-Zionist groups, including an allegation that one appointee had once claimed “Zionists are worse than Nazis.”

Mamdani’s antisemitism and anti-Israel rhetoric are so well known that social media users were delighting in sharing old posts of Mayor Adams in support of the Jewish state, now branded with Mamdani’s name.

The National Jewish Advocacy Center concluded its letter with a warning that echoes across the political landscape: “Your first days in office will define your administration. This is not how that definition should begin.”
