"But I will say that somebody knew and if there was a reporter that sat on a story for years and didn't write it, I want to know why because I would have liked to know these stories". He was proud of that.
"When people say, 'Everybody knew, ' like yeah, I knew he was an a-hole. This level of criminal sexual predation was not something I ever thought was going on", he added.
Paltrow, 45, accused Weinstein of suggesting massages and putting his hands on her after having her come to his hotel suite for a work meeting when she was 22.
On October 10, Damon told Deadline, "I did five or six movies with Harvey". You know, I wouldn't want to be married to the guy. I didn't really necessarily believe that because to believe that would believe bad things about actresses that I know and like, and I didn't really buy into that.

In his interview alongside George Clooney, Damon said he had heard about Paltrow's incident with Weinstein from Affleck, who dated the actress after Pitt. She had handled it, and she was the First Lady of Miramax and he (Weinstein) treated her incredibly respectfully. I knew he was an a**hole. Pitt later confronted Weinstein, who later told Paltrow never to tell anyone else about what happened. "I didn't think they were going to have affairs with Harvey - and clearly they didn't".
Since the allegations against Weinstein were first published, over 60 women have come forward to allege he sexually harassed them including Angelina Jolie, Cara Delavigne, Lena Headey and Rose McGowan.
Harvey Weinstein, who just left his one-week pyschological treatment, is now under investigation by the LAPD, since more than 40 women have come forward with allegations of sexual misconduct and harrasment against him.
However, Damon and Clooney confessed that they had no clue about the extent of the sexual harassment that allegedly took place.
The "Suburbicon" director and the film's star have been sucked into the Weinstein narrative since the scandal broke earlier this month. We have to make it safe for people to feel that they can talk about this. I think that's a little bit of a surprise to some of us.
