Roberta Kaplan, a prominent lawyer best known for ending the ban on gay marriage and her advocacy work for sexual assault victims, is leaving the law firm she formed in 2017.

Kaplan’s exit from Kaplan Hecker & Fink comes following reports to the New York Times from those who worked with her that she mistreated lawyers and cultivated an unprofessional office culture. She allegedly insulted employees, made inappropriate comments about their looks, and threatened their careers.
