On Wednesday night, the national leadership of the Democratic Socialists of America announced that it had withdrawn its conditional endorsement of Rep. Alexandria Ocasio-Cortez, the best-known DSA member in the country.

In a statement announcing the decision to withdraw its endorsement of Ocasio-Cortez, DSA’s national leadership suggested that the congressional representative’s stance on issues related to Israel and Palestine had cost her the socialist organization’s endorsement.

“A national DSA endorsement comes with a serious commitment to the movement for Palestine and our collective socialist project. … To build a socialist movement that’s capable of defeating capitalism, we must demand more from leaders in our movement,” the statement reads.

The statement specifically criticized Ocasio-Cortez’s decision to vote for a House resolution that labeled “denial of Israel’s right to exist” as an example of antisemitism and her recent participation in a panel about antisemitism.
