(JTA) — Women’s March co-founder Teresa Shook called on its current organizers to step down Monday, saying they “allowed anti-Semitism.”

In a Facebook post, Shook said Bob Bland, Tamika Mallory, Linda Sarsour and Carmen Perez “have steered the Movement away from its true course.”

“In opposition to our Unity Principles, they have allowed anti-Semitism, anti-LBGTQIA sentiment and hateful, racist rhetoric to become a part of the platform by their refusal to separate themselves from groups that espouse these racist, hateful beliefs,” Shook wrote.

The controversy surrounding the Women’s March arose from Mallory’s ties to anti-Semitic Nation of Islam leader Louis Farrakhan. Earlier this year, Mallory was criticized for not speaking out after she attended an event during which Farrakhan said “the powerful Jews are my enemy” and accused “Satanic Jews” of having a “grip on the media.”

The organizers later said Farrakhan’s statements “are not aligned with the Women’s March Unity Principles,” but also defended Mallory against criticism.
