NEW YORK -- On Monday, a chorus of Hollywood stars denounced movie mogul, who was he co-founded after being accused of sexually harassing female employees and actors.
called Weinstein's behavior "inexcusable," and Glenn Close said she's "angry and darkly sad." Dame Judy Dench found it "horrifying."
All said they had no idea.
Now, journalist Lauren Sivan is speaking out about her encounter with Weinstein, which occurred a decade ago.
In 2007, the 28-year-old was working on Long Island when she had a chance encounter with Weinstein at a dinner party.
"Here I was, a young local news anchor (who) was kind of desperate to be taken seriously at the time," Sivan said. "And here's a huge powerful man in media. He asked me what I did. I told him I worked in news, he seemed really interested."
Sivan says that night, Weinstein asked her if she wanted to tour a restaurant he owned in New York City. She agreed.
"You know, he was so warm and so friendly," Sivan said. "I didn't get anything that read he was dangerous until we got downstairs. He tried to kiss me and I pushed him off, politely. That's when he seemed to get angry or annoyed and he told me to just stand there and be quiet."
"He exposed himself and he basically pleasured himself," she continued. "And when he finished, I said to him, 'Are we done here? Can I leave?' He said, 'Yes, let's both leave.' And he walked me back through the kitchen, and that's where I met up with a friend and I got out of there."
Asked about what she'd like to tell Weinstein today, Sivan said: "I hope that he knows that you cannot go around treating women the way you did, for as long as you did, and never pay a price for it. You reap what you sow."
CBS News reached out to Weinstein's attorney multiple times but has yet to hear back.
Sivan says the last time she heard from Weinstein was the day after the dinner party. She claims he called her job and asked her out on a date, but she declined.
