The alleged crime took place at the governor's mansion on December 7, 2020 when Cuomo "intentionally and for no legitimate purpose" forcibly placed his hand under the blouse of an unnamed victim and onto an intimate body part.

Mariann Wang, an attorney for Alyssa McGrath and Virginia Limmiatis, two other women accusing Cuomo of sexual misconduct released the following statement:
My clients are enormously grateful for the courage of the women who have come forward to speak the truth about Cuomo's misconduct. Cuomo is being held to account as he should be, including by being forced to answer a criminal charge. We hope that all men who abuse their power by abusing women will see this and understand that there will be real consequences to their profoundly damaging behavior.
