Rudolph W. Giuliani, who was raised as a Roman Catholic, said in an interview with New York Magazine published on Monday that he is “more of a Jew” than George Soros, a liberal billionaire and Holocaust survivor.

Mr. Soros was born into a Jewish family in Hungary during the Nazi occupation, surviving as a child by posing as a Christian godson of a government official. As a wealthy donor to Democratic causes and politicians, he is a frequent target of right-wing attacks, many of which have been characterized as anti-Semitic.

“Don’t tell me I’m anti-Semitic if I oppose him,” said Mr. Giuliani, President Trump’s personal lawyer. “Soros is hardly a Jew. I’m more of a Jew than Soros is. I probably know more about — he doesn’t go to church, he doesn’t go to religion — synagogue. He doesn’t belong to a synagogue, he doesn’t support Israel, he’s an enemy of Israel.”

Mr. Giuliani continued, appearing to refer to campaign donations to district attorneys: “He’s elected eight anarchist D.A.’s in the United States. He’s a horrible human being.”
