(CNN) New York Gov. Andrew Cuomo on Sunday denied any prior knowledge of a mailing sent by state Democrats suggesting his primary challenger, Cynthia Nixon, would not support Jewish communities in the face of anti-Semitism.

The New York State Democratic Committee, which is effectively controlled by the two-term governor, paid for the flier, which falsely claimed Nixon supports the Boycott, Divestment, Sanctions (BDS) movement, which aims to pressure Israel over its treatment of Palestinians, and accused her of being "silent on the rise of anti-Semitism."

Nixon, who condemned "the rising hate crimes we are seeing against Muslims, Jews and many other communities" as recently as late August, slammed the mailing in a statement on Sunday, calling it "an attack not only on my children and my character, but on all New Yorkers."

"The accusation that my family promotes anti-Semitism is deeply, deeply offensive," said Nixon, who is raising her two older children in the Jewish faith and attends a New York City synagogue.

She then turned her attention to Cuomo and the state party, accusing them of employing "Trump-style divide and conquer tactics."
