Firebrand liberal congresswoman Alexandria Ocasio-Cortez and First Lady Chirlane McCray had starring roles in the controversial Women’s March in lower Manhattan on Saturday—speaking to thousands of assembled protesters despite lingering accusations of anti-Semitism against some of the organizers.

The rally, in Foley Square, was organized by an offshoot of the national group Women’s March, Inc., which founded the massive original marches protesting President Trump’s election two years ago.

The parent group came under fire earlier this year for the alleged bigotry of co-presidents Linda Sarsour, a Palestinian-American activist, and gun control activist Tamika Mallory, who has openly praised Louis Farrakhan, the anti-Semitic leader of the Nation of Islam.

The organization has since publicly renounced anti-Semitism—but not before a splinter group broke off, calling itself the Women’s March Alliance and rallying the thousands more who on Saturday held a separate march down Sixth Avenue from Columbus Circle.

“I’m at this particular march because of the lack of community the other one shows,” Midtown march attendee Katie Reidy, 33, of Westchester County, told The Post.

Neither McCray nor Ocasio-Cortez, who previously boasted of Jewish ancestry, mentioned the splintering of the city’s marches—or the underlying controversy—in their speeches. Event security barred a Post reporter from speaking with either of them.

Ocasio-Cortez also attended the Women’s March Alliance event, where she told CNN that both demonstrations had the same message.

About a half-dozen counter-protesters stood across the street and screamed “Jew haters!” and held signs saying “The Farrakhan March.”

Keynote speaker and filmmaker Agunda Okeyo was interrupted when right-wing activist Laura Loomer, who is Jewish, crashed the stage and tried to commandeer the mic, shouting, “What about the Jews?”

“The women’s march hates Jews!” she shouted repeatedly.

“Linda Sarsour’s a Jew hater! Tamika Mallory’s a Jew Hater!” she hollered as she was led away by security. “I thought Jewish women were invited! I came to your party!”
