Actress Rose McGowan led one of the many allegations against Hollywood heavyweight Harvey Weinstein. After the producer was accused of sexual harassment Thursday, McGowan called on other A-list actors to speak up through Twitter the same day.

Weinstein dealt with sexual harassment allegations for nearly three decades, according to a Thursday New York Times article. The situation arguably became more complicated when a report by Vulture Monday claimed actors Matt Damon and Russell Crowe covered up a 2004 story involving Weinstein's alleged actions.

In a series of tweets, McGowan called out Damon, while also including Ben and Casey Affleck, too. The actors garnered success with the film "Good Will Hunting," which was produced by Miramax Films — a production company founded by Weinstein.

"Hey @mattdoman what's it like to be a spineless profiteer who stays silent?" McGowan said, adding: "Ben Affleck, Casey Affleck how's your morning boys?"

McGowan also went to Twitter to call for the resignation of all board members within Weinstein's company after the allegations were publicized, saying whoever works with Weinstein is "complicit."

"Deep down you know you are even dirtier," McGowan tweeted. "Cleanse yourself."

Weinstein was fired from his company Sunday. Though many in the Hollywood community have spoken out against Weinstein's actions, fashion designer Donna Karan came to his defense in a recent statement which was quoted by the Daily Mail Tuesday. She said these women were "asking for it."

"You look at everything all over the world today and how women are dressing and what they are asking by just presenting themselves the way they do," Karan said. "What are they asking for? Trouble."

Karan is known for dressing other A-list celebrities, including sheer outfits worn by Jennifer Lopez at the 2014 Billboard Awards and Rita Ora at the 2015 Vanity Fair Oscar Party.
