In her first public comments since accusing film producer Harvey Weinstein of rape, actress Rose McGowan said she had been “Silenced for 20 years” but would not remain quiet about sexual assault and harassment.

Delivering opening remarks at The Women’s Convention in Detroit, McGowan thanked the audience “For giving me wings during this very difficult time”.

McGowan has been one of the leading voices against sexual harassment in Hollywood, and tweeted earlier this month that she was raped by a man with the initials “HW”,. The Hollywood Reporter said McGowan confirmed she was referring to Weinstein.

On Twitter, McGowan has amassed supporters and urged them to call out harassment using the #RoseArmy hashtag.

McGowan has starred in several films, including Scream, Jawbreaker, and Planet Terror, as well as the early 2000s television series Charmed.

Weinstein was fired from The Weinstein Company on October 8 after The New York Times published an expose that detailed decades of sexual harassment allegations against him.

The New York Times also reported that Weinstein paid a financial settlement of $US100,000 to McGowan in 1997 over an incident in a hotel room during the Sundance Film Festival in Utah.

Addressing The Women’s Convention, McGowan said because Hollywood is male-dominated, “We are given one view”.

My name is Rose McGowan, and I am brave, and I am you.
