New York Jewish leaders gathered Monday to call a candidate for Congress an “enemy of the State of Israel.”

Charles Barron, a Brooklyn Democrat up for the primary later this month, drew ire from ex-mayor Ed Koch, Rep. Jerrold Nadler, Councilman David Greenfield and Assemblyman Dov Hikind. The group held a press conference outside Manhattan’s Museum of Jewish Heritage to denounce Barron’s candidacy, accusing him of being an ”anti-Semite,” “bigot” and “hateful.”

Barron has publically compared Israeli treatment of the Palestinians to Nazi treatment of the Jews. The officials urged constituents to instead vote for Barron’s opponent, State Assemblyman Hakeem Jeffries.

"We have learned to live together in this city despite our different backgrounds, and his vile, vicious assailing of Israel is simply not acceptable," Koch said.

“To compare Israel to Nazis, calling what Israel’s doing genocide? Israel’s trying to survive in a tough neighborhood," Nadler said. The longtime congressman added that Israel is "not doing anything like Nazis. To even put them in the same universe is a disgrace to the English language."
