Progressive Congresswoman Alexandria Ocasio-Cortez called Israel an apartheid state in a tweet on Saturday that marked an inflection point in her increasing criticism of Israel.

“Apartheid states aren’t democracies,” she wrote in a tweet that garnered 275,000 likes.

Ocasio-Cortez has been unabashedly critical of Israeli Prime Minister Benjamin Netanyahu’s policies since joining Congress in 2018 but has stopped short of endorsing the Boycott, Divestment and Sanctions movement that her colleagues Ilhan Omar and Rashida Tlaib champion.

Ocasio-Cortez has been outspoken about the ongoing Israel-Gaza conflict and took part in a day of dueling sets of speeches on the House floor by Democratic lawmakers on Thursday on the subject.

A group of nine Democrats — Reps. Debbie Wasserman Schultz, Ted Deutch, Josh Gottheimer, Elaine Luria, Brad Schneider, Brad Sherman, Kathy Manning, Jim Costa and Lois Frankel — each gave one-minute speeches about Israel’s right to defend itself, Jewish Insider reported.

Afterwards, a group of 11 fellow Democrats — Reps. Ocasio-Cortez, Tlaib, Omar, Mark Pocan, Betty McCollum, Ayanna Pressley, Cori Bush, Jan Schakowsky, Jesús García, André Carson and Joaquín Castro — gave speeches that totaled an hour that were sharply critical of Israel.

Pressley criticized the “many [who] say that conditioning aid is not a phrase that I should utter here,” referencing the ongoing debate between progressive and moderate Democrats over conditioning the money that the U.S. gives to Israel on policy priorities. President Biden said on the campaign trail that he will not consider conditioning aid.

In her speech, the freshman congresswoman Cori Bush, who defeated a longtime pro-Israel incumbent in her Missouri primary last summer, called the capital of Israel “Jerusalem, Palestine.”
