John Fetterman

In his latest appearance on Fox News, Sen. John Fetterman called New York City Mayor Zohran Mamdani a “clown” for saying he might have Israeli Prime Minister Benjamin Netanyahu arrested if he comes to the city.

Fetterman, a staunch Israel supporter who appeared on “Hannity” Wednesday night, mocked Mamdani for threatening to order Netanyahu’s arrest on a warrant issued by the International Criminal Court but then backtracking earlier this week while admitting the city would not have the authority to do so.

“So, sit down. You know you’re a clown,” Fetterman said, directing his comments to Mamdani. “You’re just going to pander to the fringe and that’s part of your base, and I know you’re angry at Netanyahu because he killed a lot of people you admire.”

Mamdani, a democratic socialist and critic of Israel, had floated the prospect of arresting Netanyahu if he attends the United Nations General Assembly in New York City in September.

The mayor called Netanyahu a “war criminal” in reference to Israel’s military offensive in Gaza.

On Tuesday, though, Mamdani reversed course and acknowledged he did not have the authority to order Netanyahu’s arrest but urged the federal government to do so and reiterated the prime minister was not welcome in the city.

Fetterman quipped that was like him trying to ban Mamdani from Pennsylvania.

Mamdani, Fetterman said, does not criticize Iran for killing protesters and the United Nations is “intensely anti-Israel.”

After months spent criticizing former Maine Democratic U.S. Senate candidate Graham Platner, who withdrew amid an accusation of rape, and bashing Democrats for supporting him, Fetterman was asked by host Sean Hannity if he would back Republican Susan Collins in the general election.

“No, I’m staying out of it,” replied Fetterman, who then criticized Democratic Michigan Senate primary candidate Mohamed El-Sayed and other progressive candidates for their anti-Israel views.

“They’re running on, just below the surface, Jew-hating,” said Fetterman.
