Earlier today, Def Jam Records co-founder Russell Simmons announced that he will be stepping down from his current companies. The move comes after two accusers went public with accounts of sexual assault and rape in 1991. The same day, one of Simmons’ most successful acts from his Def Jam days is showing solidarity to women accusing his father of similar acts. Founding Beastie Boys member Adam “Ad-Rock” Horovitz is putting morality above relations.

On Thursday (November 30), a New York Times story reports that nine women have accused Ad-Rock’s father, accomplished playwright Israel Horovitz of sexual misconduct. The veteran playwright, screenwriter, and actor has worked with Al Pacino and Kevin Kline. The accusations against the 78-year-old Israel Horovitz range from forcible kissing to rape.

The Times’ story included a straight-forward statement from Ad-Rock, which read: “I believe the allegations against my father are true, and I stand behind the women that made them.”

Last November, at an anti-hate rally at Adam Yauch Park in Brooklyn (named after late Beasties member MCA), Ad-Rock urged those in attendance to stand up for causes. “If you’re able to protest, protest. If you’re able to give money, give to Black Lives Matter. Give to Planned Parenthood. Give to the United Way of Flint, Michigan. Give what you can. If you’re able to volunteer, volunteer…If you’re a musician, write that anthem. If you’re a writer, write. Take what you’re good at, and what you truly enjoy, and lend your services to the causes you care most about, because we can’t and we won’t and we don’t stop.” The rally took place after vandals wrote antisemitic graffiti in the park named after the Jewish MC/producer/activist.

In recent years, Ad-Rock has worked with New York Hip-Hop group Ratking, as well as advanced his acting career. He is married to Punk musician and feminist Kathleen Hanna, of Le Tigre fame. In late 2015, the Beastie Boys opened their extensive studio up to New York University students.
