18 women, made up of cast and crew from the show One Tree Hill, have joined together to write a powerful open letter accusing the show's showrunner Mark Schwahn of sexual harassment.

The reason for the group letter was to show support to one of the writers on One Tree Hill, Audrey Wauchope, who recently spoke out about how one particular showrunner (later identified as Mark) harassed a lot of the women working on the show. Sometimes it was small gestures such as touching their hair or rubbing their shoulders and other times it was more than that. Writing on Twitter she said, "One of the 1st things we were told was that the showrunner hired female writers on the basis of their looks. That's why you're here - he wants to fuck you." She went on, "Female writers would try to get the spot where the showrunner wouldn't sit as to not be touched. Often men would help out by sitting next to him, thus protecting the women." She also added, "Sometimes we wouldn't luck out and he'd just squeeze his disgusting body in between us and put his arms around us, grinning. He pet hair. He massaged shoulders. I know he did more but not to me so they're not my stories to share." Audrey bravely spoke out in light of other allegations towards powerful men in the industry. While she never actually mentioned Mark's name in the Twitter thread, 18 women from One Tree Hill have named him on her behalf. They wanted to get together to show support to her and confirm what she had said. Led by the main actresses, Sophia Bush, Hilarie Burton and Bethany Joy Lenz, they shared an open letter with Variety.

"To Whom It May Concern, All of the female cast members of One Tree Hill have chosen this forum to stand together in support of Audrey Wauchope and one another. To use terminology that has become familiar as thesystemic reality of sexual harassment and assault has come more and more to light, Mark Schwahn’s behavior over the duration of the filming of One Tree Hill was something of an “open secret.” Many of us were, to varying degrees, manipulated psychologically and emotionally. More than one of us is still in treatment for post-traumatic stress. Many of us were put in uncomfortable positions and had to swiftly learn to fight back, sometimes physically, because it was made clear to us that the supervisors in the room were not the protectors they were supposed to be. Many of us were spoken to in ways that ran the spectrum from deeply upsetting, to traumatizing, to downright illegal. And a few of us were put in positions where we felt physically unsafe. More than one woman on our show had her career trajectory threatened. The through line in all of this was, and still is, our unwavering support of and faith in one another. We confided in each other. We set up safe spaces to talk about his behavior and how to handle it. To warn new women who joined our ranks. We understood that a lot of it was orchestrated in ways that kept it out of sight for the studio back home. We also understood that no one was fully unaware. The lack of action that has been routine, the turning of the other cheek, is intolerable. We collectively want to echo the calls of women everywhere that vehemently demand change, in all industries. Many of us were told, during filming, that coming forward to talk about this culture would result in our show being canceled and hundreds of lovely, qualified, hard-working, and talented people losing their jobs. This is not an appropriate amount of pressure to put on young girls. Many of us since have stayed silent publicly but had very open channels of communication in our friend group and in our industry, because we want Tree Hill to remain the place “where everything’s better and everything’s safe” for our fans; some of whom have said that the show quite literally saved their lives. But the reality is, no space is safe when it has an underlying and infectious cancer. We have worked at taking our power back, making the conventions our own, and relishing in the good memories. But there is more work to be done. We are all deeply grateful for Audrey’s courage. For one another. And for every male cast mate and crew member who has reached out to our group of women to offer their support these last few days. They echo the greater rallying cry that must lead us to change: Believe Women. We are all in this together.
