New York City Mayor Zohran Mamdani says his administration is exploring whether it can arrest Israeli Prime Minister Benjamin Netanyahu, a move CNN's own legal analyst called "utterly ridiculous" and legally impossible.
Elie Honig, a CNN legal analyst and former federal prosecutor, delivered a blunt on-air rejection Monday of Mamdani's suggestion that New York City possesses any authority to detain a visiting foreign head of state. Asked by CNN anchor Brianna Keilar for a "reality check," Honig did not hedge.
"Absolutely not," Honig said. He then laid out, point by point, why the mayor's legal position has no foundation in federal law, the Constitution, or the city's own powers.
Mamdani had told The New York Times that Netanyahu is a "war criminal" who "belongs in The Hague." His administration, the mayor said, is in "active conversation" with the New York City Law Department about what legal authority the city might wield should Netanyahu visit, potentially for the United Nations General Assembly.
Honig's first point was structural. The mayor of New York City, he said, has "zero law enforcement authority." He does not direct the Manhattan District Attorney. He does not tell the NYPD, the city's police force, whom to arrest or whom to indict. Those offices operate independently.
His second point concerned the warrant itself. The International Criminal Court issued arrest warrants for Netanyahu and former Israeli Defense Minister Yoav Gallant in November 2024, citing alleged war crimes and crimes against humanity tied to Israel's military campaign in Gaza. But the United States is not a signatory to the ICC's founding treaty. That warrant, Honig told Keilar, "has zero legal effect here in the United States."
Honig went further. He cited a U.S. federal law, passed roughly 24 years ago, that authorizes the president to send military troops to extract American personnel and allied individuals from ICC custody if necessary. Congress built that statute specifically to prevent the ICC from exercising jurisdiction over Americans or their allies on U.S. soil.
And his final point was constitutional. The conduct of foreign diplomacy and foreign affairs belongs exclusively to the federal government, not to a city hall.
Honig offered Mamdani's lawyers some free advice:
"I know the mayor is having his best lawyers look at this right now. Let me save them some time. You do not have the authority to do this."
At an unrelated press conference Monday, Mamdani did not back down. He framed his position as a straightforward matter of honoring international law, regardless of the target.
"When it comes to Benjamin Netanyahu, we are talking about someone who's the subject of an international criminal court arrest warrant. And he's the subject of the arrest warrant for alleged crimes against humanity for war crimes, and he's the architect of the genocide of Palestinians in Gaza as Israel's prime minister. These are not facts of my personal assessment; they are facts of public record."
Mamdani added that he believes ICC warrants "should be honored" whether the subject is Netanyahu, Russian President Vladimir Putin, "or whomever else." He also pledged that his administration would "follow all applicable local laws", a carefully worded commitment that leaves open the question of whether those laws could somehow be stretched to cover a foreign head of state.
He did clarify one boundary: his administration would not write new laws for the purpose of arresting Netanyahu.
When Fox News Digital reached Mamdani's office for comment, a spokesperson referred reporters to his Monday press conference statement.
Mike Waltz, the U.S. Ambassador to the United Nations, responded Monday on X with a post dismissing Mamdani's remarks as "pure political theater." Waltz laid out four legal barriers: the United States is not party to the ICC's founding treaty, the U.N. Headquarters Agreement protects visiting heads of government, head-of-government immunity applies, and "federal authority trumps any local mayor's wishes."
Waltz's rebuttal tracks closely with Honig's analysis. Both men arrived at the same conclusion from different vantage points, one as a legal analyst, the other as the administration's senior diplomat at the U.N., and neither left room for ambiguity. The mayor has no legal mechanism to do what he is publicly exploring.
Mamdani's "active conversation" with the city's Law Department has not, by any public account, produced a formal legal opinion. No legal authority has been identified. No mechanism has been described. The mayor himself acknowledged that his administration will follow local law, which, as Honig explained, grants the mayor no arrest power over anyone, let alone a foreign head of state shielded by federal supremacy, diplomatic immunity, and a treaty the United States never signed.
What the mayor did accomplish was a public declaration, one that positions him on the political left of the Israel debate and generates headlines. Netanyahu has not confirmed plans to visit New York City. The ICC warrant that Mamdani wants honored carries no legal weight in the United States. And the federal government has made clear, through both law and its ambassador, that it will not permit a city mayor to freelance on foreign policy.
The Constitution does not leave foreign affairs to local officials for a reason. When a mayor starts shopping for legal authority to arrest a sitting allied head of state over a warrant his own country does not recognize, the question is not whether the law allows it, it plainly does not. The question is who the performance is for.
