The Southern Poverty Law Center will not sponsor the Women’s March on Washington this year amid allegations of anti-Semitism among the group’s national leadership.

Jen Fuson, a spokeswoman for the SPLC, told The Daily Beast that “other projects” took priority over the Jan. 19 protest but that the organization would still be involved in some marches at the local level.

This comes after the SPLC in 2017 designated itself an “official supporter” of the Women’s March and its “mission to bring together communities insulted, demonized and threatened by the rhetoric of the past election cycle.”

Ms. Fuson would not confirm that the SPLC’s decision was due to allegations of anti-Semitism within the national group’s ranks.

The march and its national co-chairs Bob Bland, Tamika Mallory, Carmen Perez and Linda Sarsour have faced widespread backlash following an explosive report in Tablet magazine that said Ms. Mallory and Ms. Perez berated a Jewish organizer using anti-Semitic stereotypes at a 2017 meeting. The co-chairs have strongly denied the accusations.

Ms. Mallory has also faced criticism for attending Nation of Islam meetings and calling its anti-Semitic black nationalist leader, Louis Farrakhan, the G.O.A.T., which means greatest of all time.
