On Friday, the local chapter of the National Organization for Women had a message for Manhattan District Attorney Cy Vance.

"There is evidence you can't refute. DA Vance should prosecute!" the group chanted.

Two years ago, Vance's office declined to prosecute entertainment executive Harvey Weinstein, even after he appeared to be caught on an NYPD surveilance tape admitting to groping an Italian actress.

"The district attorney absolutely had enough evidence to prosecute Harvey Weinstein," said Jane Manning of the National Organization for Women. "The victim's account alone was legally sufficient. The tape obtained by the NYPD investigation provided extra."

Some career prosecutors said the case was not winnable in a court of law, but the stories of predatory behavior against Weinstein are so explosive, it's created a ripple of fear in New York political circles, since Weinstein was a major donor to New York's Democratic political class. 

Senators Charles Schumer and Kirsten Gillibrand have given back donations or donated them to charity. And on Thursday, Governor Andrew Cuomo announced he would return more than $100,000 from Weinstein after initially pledging to give back a portion of that.

Vance, who's running for re-election this year, took money from Weinstein's attorney shortly after he dropped the case.

Some have called on Attorney General Eric Schneiderman to investigate. He was asked about Friday.

"I have known Cy Vance for a very long time, before either of us had these jobs. We were on the sentencing commission together, and I’ve always found him in his dealings with me to act with utter integrity," Schneiderman said.

But it's not just the Weinstein case. Vance has also come under fire for failing to prosecute President Donald Trump's two oldest children as part of a real estate deal.

Last week, WNYC reported that Trump declined to prosecute Ivanka and Donald Trump Jr. over the Trump SoHo Hotel and condominium. Investors accused the Trumps of misrepresenting how successful the project was.

"It could have changed the course of history if Ivanka and Donald Trump Jr. would have been indcited for fraud," said Sonia Ossorio of the National Organization for Women.

Vance also took donations from Trump's attorney, all of which have snce been returned.
