Next tonight, New York City Mayor Eric Adams is accused of sexually assaulting a woman 30 years ago. The woman is making the accusation in a court filing under a New York state law which gave victims of sexual violence a one year window to sue over attacks that took place decades ago. Adams is vigorously denying the accusation. Here's ABC senior investigative reporter Aaron Katursky.

Tonight, the mayor of New York is accused of sexually assaulting a woman 30 years ago. In a new court filing, the woman alleges she was sexually assaulted by defendant Eric Adams in 1993 while they both worked for the city of New York. Today, Adams said he doesn't know the woman, calling the allegation absolutely not true.

Something absolutely that has never happened, and I don't even recall ever meeting a person who made this allegation.

The woman filed her claim just before the midnight expiration of New York's Adult Survivors Act. The temporary law signed last year by Governor Kathy Hoekel allows adult sexual misconduct accusers to file lawsuits that previously would have been barred by the statute of limitations. Under the same law, E. Jean Carroll successfully sued former President Trump for at least $5 million. And in the past week, Jamie Fox, Guns N'Roses Frontman, Axel Rose and Sean Diddy Combs also faced adult survivors. Act lawsuits. Fox and Rose denied the allegations. Combs also denied, then settled. The mayor's accuser filed a notice that does not include specifics of the alleged encounter, but broadly accuses Adams of causing physical, psychological and other injuries suffered as a result of conduct that would constitute sexual offenses. She's seeking at least $5 million.

This is a precursor to a formal complaint that would have to lay out the details of the woman's accusations. Lindsay she's also accusing the city and the NYPD of discrimination, so she'll have to spell out those accusations as well.
