Ocasio-Cortez told a cheering crowd Saturday that justice was "not a concept we read about in a book," while referencing issues of inequality such as vote access and unequal pay for women in the workplace.

"Justice is about the water we drink. Justice is about the air we breathe. Justice is about how easy it is to vote," Ocasio-Cortez said Saturday. "Justice is about if we can stay with our children after we have them for a just amount of time. Mothers, fathers, and all parents."

Her address at the third annual Women's March in New York comes as the movement has been criticized by some after one of the organizers, Tamika Mallory, refused to completely condemn Nation of Islam leader Louis Farrakhan during a recent interview. Farrakhan has a history of anti-Semitic statements.

Mallory's refusal to disassociate herself completely from Farrakhan led to the withdrawal of several Democrats who previously supported the march, including former Democratic National Committee chairwoman and Jewish congresswoman Rep. Debbie Wasserman Schultz Deborah (Debbie) Wasserman SchultzFlorida Democrat introduces bill to recognize Puerto Rico statehood referendum Five things to watch at the Democratic National Convention Michelle Obama wishes Barack a happy birthday: 'My favorite guy' MORE (D-Fla.).

"I cannot associate with the national march’s leaders and principles, which refuse to completely repudiate anti-Semitism and all forms of bigotry," Wasserman Schultz wrote in an op-ed. "I cannot walk shoulder to shoulder with leaders who lock arms with outspoken peddlers of hate."

Ocasio-Cortez said Saturday during an interview with CNN, that it was "absolutely valid" to worry about anti-semitism from the Trump administration.

"I think that concerns of anti-Semitism with the current administration in the White House are absolutely valid and we need to make sure that we are protecting the Jewish community and all those that feel vulnerable in this moment," she said.
