On a day when Sen. Bernie Sanders wrapped up another primary win, a rally in Harlem turned ugly when a man in the audience took the microphone and ranted about “Zionist Jews” controlling Wall Street and the banks.

According to The Hill, the man used his chance to ask the Vermont senator a question from the floor and it quickly turned ugly.

Prefacing his question, the man cited Sanders’ Jewish ancestry and the fact that he spent a year in Israel, before continuing, “As you know, the Zionist Jews – and I don’t mean to offend anybody – they run the Federal Reserve, they run Wall Street, they run every campaign.”

Sanders immediately began wagging his finger at the man and shaking is head no, while repeating, “Brother, brother, brother.”

As the crowd began booing, the man shouted, “What is your affiliation to your Jewish community? That’s all I’m asking.”

“No, no, no,” Sanders retorted. That’s not what you’re asking.”

As the crowd grew rambunctious, Sanders tried to defuse the situation.

“I am proud to be Jewish, ” he asserted to applause. “But you’re not going to find any candidate running for president, for example, talking about Zionism and the Middle East.”

He stated that he supports Israel before adding, “I also believe that we have got to pay attention to the needs of the Palestinians!”

As the crowd cheered wildly, Sanders continued, “There are good people on any side of an issue, and there are bad people on any side of an issue. But if we are going to bring peace, hopefully, God willing, in the Middle East, we’re going to have to treat both sides with respect and equality, alright?”
