Ashley Judd, who sued Weinstein earlier this year alleging he damaged her career in retaliation for turning down his advances, tweeted a statement late Friday that called the charges "a watershed event."
Accuser Asia Argento, who has claimed Weinstein forced oral sex on her in 1997, didn't mince words when she tweeted, "Today Harvey Weinstein will take his first step on his inevitable descent to hell. We, the women, finally have real hope for justice."
“The Hand that Rocks the Cradle” actress Annabella Sciorra, who has accused the former producer of rape in the early 1990s, has been tweeting ever since it was announced Thursday that Weinstein would be turning himself into police.
"Can’t wait!" she wrote after the news broke, followed by, "Anyone know where I can get front row seats?!"
Time's Up, an organization born out of the Weinstein scandal that is dedicated to fighting inequality and injustice in the workplace, also posted a lengthy note online.
"Today a man whose actions were so egregious that they spawned a global reckoning has been taken into custody," the statement read. "Harvey Weinstein shattered the lives of an untold number of women. We stand with them, and remain in solidarity with women everywhere who have faced unsafe and abusive workplaces. We look forward to seeing justice prevail."
Actress and photographer Katherine Kendall, who told ABC News’ “Nightline” that after she refused to give Weinstein a massage in the early ‘90s, he asked her to show him her breasts, says she feels “so surreal.”
“It felt like a real victory,” Kendall told “Nightline.” “He deserves his day in court and so do we.”
“I keep thinking of all the women that I've talked to and I met over this period of time who have worked so hard and been so brave and have suffered so much and put themselves on the line to commit to bringing him down because they believe he deserves that,” Kendall added. “They were you know put through the wringer and I can't help but think of those women right now.”
