One of the women, Michelle Manning Barish, described to The New Yorker being slapped by Mr. Schneiderman so violently and abruptly one day it left one of her ears ringing. Ms. Manning Barish said that when she tried to fight back, Mr. Schneiderman pushed her onto a bed, pinned her down with his body weight and then began to choke her.

Ms. Manning Barish said Thursday that she felt “completely vindicated” by Mr. Schneiderman’s apology, which she took as an admission that he had abused her and her fellow accusers. But she called on him to go further and to donate the millions of dollars he collected for his abandoned re-election campaign to groups that combat sexual violence against women.

“This is a victory for all women, but we need more than words,” she said in a written statement.

In October, another accuser, Tanya Selvaratnam, wrote an opinion article for The New York Times, detailing how Mr. Schneiderman often slapped her until she agreed to call him “master” and sometimes referred to her as his “property.”

Ms. Selvaratnam also claimed that Mr. Schneiderman frequently belittled her looks and told her that he could tap her phone and have her followed.

“This wasn’t just cruel or weird sex,” she wrote. “It was one element in a larger dynamic of power and control.”

On Thursday, Ms. Selvaratnam thanked Ms. Singas “for the care she gave to the investigation.” She added that “this experience underscores the need for legislation addressing intimate violence.”

After the allegations were made public, many of Mr. Schneiderman’s allies, including Mr. Cuomo and Senator Kirsten E. Gillibrand, moved swiftly in asking him to step down. Within two weeks, the New York Legislature voted to confirm Barbara D. Underwood, the state’s top appellate lawyer, as Mr. Schneiderman’s replacement, making her the first woman to hold the post of state attorney general. (On Tuesday, Letitia James, the former New York City public advocate, was elected to the job.)
