Cynthia Nixon has come under scrutiny by members of the Democratic Socialists of America, which will soon decide whether to endorse her.

An essay posted Monday, signed by dozens of members, urged a no vote, noting, "Nixon is a multi-millionaire who has donated less than five percent of her income to charity."

"In any organization, there's going to be differences of opinion," Nixon said.

A rebuttal essay Tuesday argued her case, noting her working class upbringing and her education advocacy.

"Nixon's wealth originates from a career in television, not as the result of benefitting over home foreclosures or other forms of anti-social financial investments," the essay reads.

She said the group has moved progressive issues front and center. "Until we start fighting for things like single-payer health care and housing as a right, our Democratic voters are not going to be incentivized to turn out," Nixon said.

Meanwhile, Nixon was at a subway station Monday, blasting Gov. Andrew Cuomo for the city's continuing transit woes.

It was another familiar critique Tuesday, as Nixon again highlighted the underfunding of schools and the criminalization of youth in low-income communities of color.

"For too long, our governor here has been content to see two different New Yorks," Nixon said. "In one New York, white wealthy children are given a sound basic education and are treated fairly by the criminal justice system. In the other New York, a child's fate is determined by his or her zip code."

Nixon joined students and community activists outside P.S. 19 in Queens, which she said is owed nearly $3 million in state aid.

Her Democratic primary opponent, however, has pushed back hard on Nixon's narrative. Cuomo's campaign said school aid has gone up every year, with more than three-quarters now going to the neediest schools.

Cuomo also notes that it is the city that distributes state aid and the city has not disclosed spending on a school-by-school basis.
