An emotional Ashley Judd spoke with ABC News' Diane Sawyer about coming forward with her account about producer Harvey Weinstein trapping her in his hotel room, in the midst of what she thought was a business meeting. "I didn't expect that I would feel tearful," Judd said, "but It's been an absolutely tremendously moving two and a half or three weeks."

While dozens of women, including stars like Gwyneth Paltrow and Angelina Jolie, aspiring actresses, and former employees, have now accused Weinstein of sexual harassment and even assault, Judd was the first celebrity to come forward in the NY Times' bombshell report earlier this month. The article led with her divulging her shocking alleged encounter with Weinstein in 1997: "Two decades ago, the Hollywood producer Harvey Weinstein invited Ashley Judd to the Peninsula Beverly Hills hotel for what the young actress expected to be a business breakfast meeting. Instead, he had her sent up to his room, where he appeared in a bathrobe and asked if he could give her a massage or she could watch him shower..."

Judd had alluded to the incident in a 2013 Variety article, but never mentioned Weinstein by name, for fear of being smeared by the Oscar-winning producer's formidable legal and publicity machine. But she said after she went on run she made the decision to talk to the Times on the record.

And when she told her mother, country star Naomi Judd, her mother said, "Go get him."

Part of the interview aired on Good Morning America (other parts are airing on World News Tonight with David Muir and Nightline, as well as on the ABC News website), and Judd declared "I had no warning" regarding Weinstein's behavior.

"I remember the lurch when I went to the [hotel] desk," she recalled when she was told that Weinstein was in his hotel room (she was told the meeting would be on the patio). "'Ugh, are you kidding me?'...[but this was] his pattern of sexual predation. That was how he rolled."

She went to his room because she had a "business appointment," but once there, she felt trapped by him, as he asked her to give him a massage and then watch him shower. "There's this constant grooming, negotiation going on... I thought no meant no... I fought with this volley of no’s, maybe they turned him on, I don't know," she said.

Judd explained that she refused to sit down and described how she managed to get out of the room: "When I win an Oscar in one your movies," she would agree to touch him. Weinstein allegedly replied, "Yeah, when you get nominated," but Judd insisted, "No, when I win an Oscar."

On whether she feels conflicted about how she handled it, Judd said she is ultimately proud that she got out of the room, "We all do the best we can and our is best good enough. It's really okay to have responded to the way we responded."

Regarding the 1997 photograph of her with Weinstein and Vince Vaughn, Judd said that she had hoped she wouldn't see him at a party but he grabbed her: "The look in my face is abject terror. It's very gross. It's very gross. I feel for that 28-, 29-year-old woman."

Weinstein, who was fired from his production company, The Weinstein Company, has admitted bad behavior with women but has denied accusations of assault. The NYPD is investigating a 2004 rape claim, detailed in the New Yorker, against him.
