NEW YORK -- The Manhattan District Attorney's office is investigating allegations of violence against women by New York Attorney General Eric Schneiderman, who resigned just hours after accounts of abuse by four women. It was a swift and stunning fall for a Democrat who held himself out as a champion of women and a liberal foil to President Trump and who pledged to use his office to hold others accountable for abusing their power.

The women described being slapped and choked, verbally abused and threatened by Schneiderman. Some also described him as a heavy drinker.

The abuse often happened during what were supposed to be romantic encounters, but the women said the violence was not consensual.

Schneiderman, 63, implied in a statement that his conduct was either welcomed by the women, or was not as they described.

"In the privacy of intimate relationships, I have engaged in role-playing and other consensual sexual activity. I have not assaulted anyone. I have never engaged in non-consensual sex, which is a line I would not cross," he said.

Statement from Eric T. Schneiderman: "In the privacy of intimate relationships, I have engaged in role-playing and other consensual sexual activity. I have not assaulted anyone. I have never engaged in non-consensual sex, which is a line I would not cross." — Eric T. Schneiderman (@Schneiderman) May 7, 2018

Danny Frost, a spokesman for Manhattan District Attorney Cyrus R. Vance Jr., said in a statement late Monday that prosecutors would look into the claims.

It's an unusual twist: Schneiderman's office had been tasked with investigating the Manhattan District Attorney's office over its handling of a 2015 sex assault probe involving Harvey Weinstein that resulted in no criminal charges.

The NYPD has told CBS News that they have no complaints on file. They said if they receive complaints of a crime, it will investigate them thoroughly.

The state's Solicitor General, Barbara Underwood, will serve as acting Attorney General. She has a long history of legal work including serving in the Eastern District of New York and in the Manhattan, Brooklyn and Queens district attorney offices.

Schneiderman, a prominent #MeToo supporter, capitulated quickly after fellow Democrats in New York, including Gov. Andrew Cuomo and U.S. Sen. Kirsten Gillibrand, called for his resignation.

Schneiderman later issued the following statement: "It's been my great honor and privilege to serve as Attorney General for the people of the State of New York. In the last several hours, serious allegations, which I strongly contest, have been made against me. While these allegations are unrelated to my professional conduct or the operations of the office, they will effectively prevent me from leading the office's work at this critical time. I therefore resign my office, effective at the close of business on May 8, 2018."

Two women who spoke to The New Yorker on the record, Michelle Manning Barish and Tanya Selvaratnam, both said the physical abuse escalated over time. The Associated Press is identifying the women because they agreed to tell their stories publicly.

"After the most difficult month of my life-I spoke up. For my daughter and for all women. I could not remain silent and encourage other women to be brave for me. I could not," Manning Barish wrote on Twitter after the story was published.

Manning Barish said she was involved with Schneiderman from mid-2013 through the end of 2014. Selvaratnam said she was involved with him from the summer of 2016 until fall 2017.

Manning Barish said Schneiderman became violent a few weeks after they began dating. She said she confided in friends, including novelist Salman Rushdie.

Selvaratnam, who was born in Sri Lanka, said Schneiderman started calling her his "brown slave" and made her say that she was "his property."

"After I found out that other women had been abused by Attorney-General Schneiderman in a similar manner many years before me, I wondered, who's next, and knew something needed to be done," Selvaratnam said in a statement to the AP.

Schneiderman has been a vocal supporter of the #MeToo movement. He filed a lawsuit in February against Weinstein and the Weinstein Co. following an investigation into allegations of sexual misconduct. Schneiderman said the company broke New York law by failing to protect employees from "pervasive sexual harassment, intimidation and discrimination."

He launched a civil rights probe into the New York City-based company in October after The New York Times and The New Yorker exposed allegations of sexual assault and harassment spanning decades. The company later fired Weinstein.

The women accusing Schneiderman said seeing him speak out on these issues was part of what prompted them to come forward.

The former state senator became attorney general in 2010 and had been running for re-election this year. He also has been a longtime critic of Trump, and has been part of several efforts to push back against some of his actions in the White House, like the rescinding of protection for immigrants brought to the U.S. illegally as children.

Last month, he urged state lawmakers to close a loophole that he said could be used to fight state charges by anyone who has received a federal pardon for similar federal charges.

On Twitter, Donald Trump Jr. offered pointed commentary. He showcased one of Schneiderman's tweets from last year saying that he would remind President Trump that no one was above the law, with Trump Jr. adding, "You were saying-?"
